description: Human cultured leukemia cells appear to have a decreased amount of inosine in their tRNA. When cells with inosine deficient tRNA are placed in a hypoxanthine fortified media, they incorporate hypoxanthine into their tRNA by the action of the enzyme tRNA-hypoxanthine ribosyl transferase. This generates the nucleoside inosine in the tRNA. The cultured human leukemia cell lines, CCRF-CEM, HL-60, and HGPRT(-) HL- 60, incorporate hypoxanthine into their tRNA, as determined by tRNA isolation, hydrolysis, and HPLC analysis. Hypoxanthine treatment dramatically inhibited cell growth in conjunction with partial induction of differentiation in the CCRF-CEM, HL-60, and HGPRT ( - ) HL-60 cells cultures. Immunofluorescent analysis of surface differentiation antigens for CCRF-CEM cells established differences that indicated a progression towards a more differentiated phenotype. The HL- 60 and HGPRT(-) HL-60 cells morphologically and functionally differentiated after exposure to hypoxanthine as determined by differential counts and NBT reduction. These results suggest that hypoxanthine induced differentiation of these human cultured leukemia cells is due to the concurrent modification of tRNA with hypoxanthine to form inosine.

description: Nicotinamide Phosphoribosyltransferase (NAMPT) is a rate-limiting enzyme in the biosynthesis of NAD. Cancer cells have elevated poly [ADP-Ribose] polymerase 1 (PARP) activity as well as the immense necessity of ATP: thereby consuming NAD at a higher rate than normal tissues. The perturbation of these intracellular processes is more sensitive and highly dependent on NAMPT to maintain the required NAD levels. Functional inhibition of NAMPT is, therefore, a promising drug target in therapeutic oncology. In this study, the importance of intermolecular contacts was realized based on contact occupancy and favorable energetic from molecular dynamic simulation to discern non-critical contacts of four different classes of potential NAMPT inhibitor bound complexes. Further, pharmacophore modeling, molecular docking, a quantum mechanical properties and MD simulation, as well as active site residual network communication were employed to identify potential leads. Present studies identified two leads, 2 and 3 which have better binding free energy compared to known inhibitors and showed stable hydrogen bonding and hydrophobic contacts with β barrel cavity lining residues in the active site of the dimer interface (A′B). Lead 2 containing fluorene as central core and lead 3 having phenyl-benzamide as a core showed stable moiety which was observed from electronic property analysis. Active site residual communication in identified leads bound complex also showed similarity to known inhibitor complexes. Compounds containing these moieties were not reported until now against NAMPT inhibition and can be considered as novel cores for future development of drugs to inhibit NAMPT function.

description: Autocorrelation sequence prediction is one of the hotspots in machine learning and statistics. At present, the problem of epidemic prediction is concerned by the whole world in this field. In this paper, a prediction algorithm of autocorrelation sequence based on transformation is proposed. It construct a reference function based on the time series of regions that have experienced the whole process of epidemic situation. The reference function coordinates are transformed with the incomplete observation data of other regions as the supervision. Under the condition that the cost of transformation is kept as small as possible, the transformed function can effectively predict the series values that are not observed in other regions. This algorithm needs a little data and has good training stability. On this basis, we study how to use the information provided by other exogenous variables on the basis of autocorrelation prediction to make the model achieve better results. We use the covid-19 epidemic data set provided by Baidu to test our model, and the results show that it has good fitting metrics. It also has better effect in comparison with LSTM epidemic prediction model baseline.

description: Recent growth in unmanned aerial vehicle (UAV) technology have promoted the detailed mapping of individual tree species. However, the in-depth mining and comprehending of the significance of features derived from high-resolution UAV data for tree species discrimination remains a difficult task. In this study, a state-of-the-art approach combining UAV-borne light detection and ranging (LiDAR) and hyperspectral was used to classify 11 common tree species in a typical natural secondary forest in Northeast China. First, comprehensive relevant structural and spectral features were extracted. Then, the most valuable feature sets were selected by using a hybrid approach combining correlation-based feature selection with the optimized recursive feature elimination algorithm. The random forest algorithm was used to assess feature importance and perform the classification. Finally, the robustness of features derived from point clouds with different structures and hyperspectral images with different spatial resolutions was tested. Our results showed that the best classification accuracy was obtained by combining LiDAR and hyperspectral data (75.7%) compared to that based on LiDAR (60.0%) and hyperspectral (64.8%) data alone. The mean intensity of single returns and the visible atmospherically resistant index for red-edge band were the most influential LiDAR and hyperspectral derived features, respectively. The selected features were robust in point clouds with a density not lower than 5% (~5 pts/m2) and a resolution not lower than 0.3 m in hyperspectral data. Although canopy surface features were slightly different from original LiDAR features, canopy surface information was also important for tree species classification. This study proved the capabilities of UAV-borne LiDAR and hyperspectral data in natural secondary forest tree species discrimination and the potential for this approach to be transferable to other study areas.

description: Curdione (1), a sesquiterpene with a germacrane skeleton from rhizomes of Curcuma wenyujin, has attracted attention due to its important pharmacological properties. Herein, we investigated the chemo-biotransformation of curdione (1) systematically using Aspergillus niger AS 3.739. Regio- and stereoselective hydroxylation of curdione with filamentous fungus A. niger AS 3.739 led to seven metabolites including four new compounds 3α-hydroxycurcumalactone, 2β-hydroxycurcumalactone, (10S)-9,10-dihydroxy-curcumalactone and (10R)-9,10-dihydroxy-curcumalactone. Their structures were determined by spectroscopic techniques including two-dimensional NMR and TOF-MS (Time of Flight Mass Spectrometry). Based upon the analysis of biological and chemical conversions of curdione, a tentative metabolic pathway via chemo-bio cascade reactions is proposed in A. niger system, which provides an insight into the corresponding metabolism of curdione in animal systems. In addition, experiments with selected monooxygenase inhibitors suggest that cytochrome P450 monooxygenase played a crucial role in the hydroxylation of curdione.

description: Four chlorinated depsidones (two reported for the second time (1 and 2) and two known (3 and 4)) were isolated from a seaweed-derived Aspergillus unguis strain. Their structures were spectroscopically elucidated. Compounds 1, 3 and 4 strongly inhibited methicillin-resistant Staphylococcus aureus (MRSA) with minimum inhibitory concentrations (MICs) of 2, 2 and 4 μg/mL and killed Artemia larva with LC50 of 4.1, 1.7 and 2.8 μg/mL, respectively. Besides, in DNA-damaging test, they also selectively inhibited a DNA repair capacity-defective Escherichia coli strain AB3027( − ) (MICs: 2, 32 and 4 μg/mL, respectively) compared with the wild-type strain AB1157(+) (MICs: over 512, over 512 and 256 μg/mL, respectively). Furthermore, compound 1 also strongly inhibited cancer cell line A-549 (IC50: 0.5 μg/mL). The above-mentioned bioactivities were newly reported for compound 1. In contrast, compound 2 did not exhibit significant activity. The structure–activity relationship indicated that a complete lactone ring may be important.

description: A strapped calix[4]pyrrole (2) with a fluorogenic pyrene unit linked to the rigid strap via the methylene bridge has been synthesised. It was established by 1H NMR and fluorescence spectroscopic analyses and isothermal titration calorimetry (ITC) studies that receptor 2 is capable of binding the F−, Cl−, (ppi) and anions in organic media, with high selectivity for F− being observed relative to the other anions. Upon exposure to the F− and , the fluorescence of 2 is quenched, an effect ascribed to facilitated PET (photo-induced electron transfer) from the nitrogen atom to the pyrene moiety, which is induced by anion binding. In contrast, the fluorescence of 2 was enhanced upon treatment with the HSO4− anion as the result of the PET inhibition that results from nitrogen atom protonation. A single crystal X-ray structure of the chloride complex of 2 and the 1H NMR spectral data revealed that the chloride anion is bound to the receptor via aliphatic C–H•••Cl− hydrogen bonds, as well as N–H•••Cl− interactions.

description: Two reasons justify the following translation. Firstly, this remarkable text is very rarely included in compilations of Seneca’s work, missing from both the Penguin and Oxford selections; as a result, the most readily available translation perhaps remains that of J.W. Basore’s Loeb from 1932.The only published recent translation is that of J.M. Cooper and J.F. Procopé (1995), who translate the title as On the Private Life and preserve some of the more old-fashioned language of Basore.4 The only modern edition of the Latin text with English commentary is G.D. Williams’s, which waspublished in 2003 and was the text used for this translation.The second reason concerns the translation itself. While there is not the space to compare closely my translation with the existing ones (all good in their own way), there are a few points worth making.

description: A new prenylated indole derivative 3-acetonylidene-7-prenylindolin-2-one (1) was isolated from the endophytic actinobacterium Streptomyces sp. neau-D50, together with four known hybrid isoprenoids, 7-isoprenylindole-3-carboxylic acid (2), 3-cyanomethyl-6-prenylindole (3), 6-isoprenylindole-3-carboxylic acid (4) and 7,4′-dihydroxy-5-methoxy-8-(γ,γ-dimethylallyl)-flavanone (5). The structures of these compounds were elucidated on the basis of extensive spectroscopic analysis and comparison with data from the literature. Compounds 1 and 2 demonstrated strong cytotoxic activities against human lung adenocarcinoma cell line A549 with an IC50 of 3.3 and 5.1 μg mL− 1, respectively, which are comparable to that of the positive control doxorubicin (4.2 μg mL− 1). Furthermore, compounds 1–4 exhibited potent antifungal activity against phytopathogenic fungi Colletotrichum orbiculare, Phytophthora capsici, Corynespora cassiicola and Fusarium oxysporum.

description: In this study, the activity of essential oils (EOs) against microorganisms involved in oral diseases was evaluated. Fourteen EOs were selected and subjected to gas chromatographic analysis, including Illicium verum, Eucaliptus globulus, Eugenia caryophyllata, Leptospermum scoparium, Mentha arvensis, Mentha piperita, Myrtus communis, Salvia officinalis, Melaleuca alternifolia, Rosmarinus officinalis, Lavandula x intermedia, Thymus capitatus and Thymus vulgaris. These EOs were tested for their antimicrobial activity on Streptococcus mutans and Lactobacillus species clinically isolated from dental surgery patients. The antibacterial activity was evaluated by means of the disc diffusion and the minimum inhibitory concentration (MIC). Five EOs, having shown an interesting antimicrobial activity, were selected for a second screening in combination between them and with chlorhexidine. From the second assays, two EO–EO and three EO-chlorhexidine associations gave interesting results as potential constituents of mouthwashes, especially for the contribution of oxygenated monoterpenes, including menthol, thymol and carvacrol.
Personal Recovery and Borderline Personality Disorder
Creators: name: Donald, Fiona
Publisher: name: Monash University
Year: 2017
Subjects: Clinical Psychology

description: The overarching focus of this thesis is to better understand processes of positive change in Borderline Personality Disorder (BPD). The concept of personal recovery is of importance to this thesis because central to the theoretical basis of personal recovery is the view that it is possible to change in positive ways while living with mental illness. However, much of the existing literature on personal recovery is focused on mental state disorders such as schizophrenia rather than on personality disorder. The focus here is on personal recovery as the concept has been developed within consumer narratives and scholarship rather than on clinical recovery as used in outcome studies of mental illness because the personal recovery literature is focused primarily on process (rather than outcome). The meaning and experience of personal recovery are explored because the recovery paradigm has been widely adopted in health services as a way of supporting individuals who are affected by mental illness, yet it is unclear how well previously established recovery principles apply to BPD. To better understand the change processes associated with recovery from BPD and assess the utility of the recovery paradigm in supporting this population, interviews were conducted with consumers diagnosed with BPD and with clinicians working within individuals with BPD. Their perspectives on the disorder, personal understanding of recovery, and beliefs about how an individual might recover from BPD were explored using thematic analysis. The relationship between self-criticism, self-compassion and recovery was also explored as self-loathing has been identified as a common difficulty for individuals with BPD and may be a barrier to recovery.

description: Decompressing inner ebullition (DIE) can reduce the extraction liquid boiling point and polyphenols oxidation in the extraction process. The aim of this study is to optimise the phenolic extraction process by DIE and to examine the antioxidant activities. The extraction process parameters were observed by central composite design. The antioxidant activity was measured using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and ferric reducing power assays. The results showed that the optimal extraction condition is extract time of 90 min, temperature of 45°C, solid–liquid ratio of 1:20 g/mL, vacuum degree of − 0.08 MPa, ethanol concentration of 60%, while the phenolic content was 5.4%. The phenolic extracts from Rhus verniciflua Stokes bark had better antioxidant activities; the antioxidant activity (IC50) of the DIE was 20 μg/mL by the DPPH method. The reducing power of the phenolic extracts was significantly related to their total phenolic content (R = 0.9903). The results presented show that the DIE method is an effective method for polyphenols extraction.

description: A series of isoquinoline alkaloids including tetrahydroprotoberberines, N-methyl tetrahydroprotoberberines and protoberberines were facile synthesised with protopines as the starting material. All compounds were evaluated for their antibacterial activities against four pathogenic bacteria Escherichia coli, Staphyloccocus aureus, Staphylococcus gallinarum and Salmonella choleraesuis. Experimental results indicated that protoberberines were the most active compounds to the target bacteria among the tested alkaloids. It was suggested that planar molecule with high aromatisation level (e.g. coptisine 5 and berberine 6) or a positive charge of the molecules (e.g. N-methyl tetrahydroprotoberberines 11 and 12) had a positive influence on the antibacterial effects.

description: 1.0 Abstract Aim: The aim of this study was to explore care leavers’ experiences of parenting. Although research has previously been carried out on this area, there is a lack of research on mature care leavers’ experiences of parenthood which this study attempts to address. It was hoped that this research might further illuminate our understanding of care leavers as parents, and highlight potential areas of clinical need and ways in which these could be addressed therapeutically. Method: This study employed a qualitative design through the use of semi-structured interviews with six care leavers who were mothers; the majority of whom were in their late 30’s to early 40’s. Interpretative Phenomenological Analysis (IPA) was used to develop a rich and multi-layered account of participants’ experiences. Results: Four main themes emerged across participants’ accounts. These were: ‘Fear of the past and its impact on the future’, ‘Trying to do better’, ‘Parenting is hard but rewarding’ and ‘Connecting and disconnecting: the push and pull.’ Implications: The study highlights the importance of holding the complexity of care leavers’ experiences as parents in mind; acknowledging both their strengths and struggles. Participants’ sense-making of their parenting in relation to their pasts as well as their resources and the processes surrounding learning to parent, were discussed in light of the themes that arose and previous theoretical and research literature. Clinical implications and recommendations for future research are also discussed.

The role of situational information in conceptual knowledge
Creators: name: Anthony, Susan Huia
Publisher: name: University of Hertfordshire
Year: 2004

description: This thesis investigated the influence of situational knowledge on the performance of two common tasks; category member generation under a free-emission procedure and the judgement of similarity between two items using rating scales. In both tasks, self-report protocols were used to identify the strategies that people seemed to be using to complete the tasks. The main goal was to identify the role of situational knowledge in the organisation of semantic memory. Traditional models would not predict a role for situational knowledge in either of the target tasks. In the category member generation studies (Chapter 2) participants frequently instantiated situations or perspectives to cue retrieval of category members for both taxonomic and ad hoc categories. Chapter 3 investigated the factors that determine subjective similarity: category type, typicality, context and presence or absence of self-report. The quantitative data analysis showed the need for careful qualifications to previous claims concerning the effect of context on similarity (Barsalou, 1982). Specifically, ad hoc category members were rated more similar with context only when judgements were made without self-report and when items were relatively typical. Self-report protocols showed that co-occurrence of items in a situation frequently entered into judgements of similarity. Chapter 4 investigated the role of events in determining the strength of this 'thematic' similarity. Individual indices of association strength between the items and an event were shown to predict similarity ratings - thus confirming that thematic similarity is driven, at least partially, by the association of items to common settings. The findings lend empirical weight to theoretical positions that present memory for situational information as an integral part of conceptual knowledge. This approach may underpin a new direction for research into concepts in both normal and clinical adult populations.

description: A 2-substituted-8-hydroxyquinoline (E)-2-[2-(3-thienyl)ethenyl]-8-quinolinol (HL) was synthesized and characterized by ESI-MS, NMR spectroscopy, and elemental analysis. Using solvothermal method, a tetranuclear complex [Cd4L6Br2]·6DMF (1) was fabricated by assembly of Cd(II) with HL. X-ray structural analysis shows that 1 exhibits a double open cubane-like core structure, which is bridged by six 8-hydroxyquinolinate-based ligands. The supramolecular structure of 1 features a 3-D porous solid constructed by aromatic stacking interactions, C–H···π interactions and C–H···O hydrogen bonds. The assembly of cadmium salts and HL in solution was investigated by UV–vis and photoluminescence. We also studied the thermal stability and photophysical properties (fluorescent emission, lifetime, and quantum yield) of 1. The results show that 1 emits yellow luminescence in the solid state.

Extraction of metals from contaminated land and industrial solid waste using a novel technology (servo process)
Creators: name: Allimann-Lecourt, Corinne
Publisher: name: University of Hertfordshire

description: Selective Extraction and Recovery using Volatile Organic compounds is an emerging technology developed during the 1970s. This process can achieve the extraction of heavy metal contaminants from a matrix using a volatile organic reagent which passes through the feed material and reacts selectively with the desired metal salt, producing a volatile metal complex, removed from the matrix by a carrier gas. Such complexes may be decomposed to produce a pure metal product and regenerate the organic reagent for recycle. Previous studies demonstrated the possible extraction of nickel from low grade laterite ores using ß-diketones (2,4- pentanedione (Hacac)) and Schiff bases (bis(pentan-2,4-dionato)propan-1,2-diimine (H2pnaa). The current research is directed towards the selective extraction of different metals such as zinc, lead, cadmium, molybdenum, and vanadium from contaminated sediments and industrial wastes (Orimulsion ash, Municipal Solid Waste fly ash (MSW), Pulverized Coal Combustion technology fly ash (PCC)). New extractants and their metal complexes have been synthesised to determine their thermal stability and their volatility. Of those synthesised the metal complexes of tetra-propyldithiophosphoramide (Hprps) are the most thermally stable. Using a thermogravimetric analyser the reaction kinetics of the SERVO process have been studied. Equipment to study the SERVO process on a laboratory scale has been designed and constructed. This equipment has been used to study the extraction of metals from four different matrices (sediments, Orimulsion ash, and two types of fly ash) using three different extractants, with promising results. These sources have been ranked from the best to the least applicable for the technology: Orimulsion ash > sediments > MSW fly ash > PCC fly ash. Of the three extractants studied, Hacac, H2pnaa and Hprps, the latter is the most efficient in terms of the range of metals which can be extracted, the volatilisation temperature, the extent of degradation and reaction time, but unfortunately is also the most expensive. For the fly ashes, of the three ligands studied, Hprps is the preferred extractant followed by H2pnaa. Hacac is not recommended for these sources because extraction is too low.

description: Here, the complete chloroplast genome sequence of Zingiber teres is described using MGI paired-end sequencing. The genome is 163,428 bp in length and contains a small single-copy region (SSC) of 15,782 bp, a large single-copy region (LSC) of 88,142 bp, and two inverted repeat (IR) regions of 29,752 bp. The overall GC content is 36.1%, and the GC content of the IR regions is 41.1%, which is higher than that of both the LSC region (33.8%) and SSC region (29.5%). The genome of Z. teres contains 133 complete genes, including 88 protein-coding genes (79 protein-coding gene species), 38 tRNA genes (28 tRNA species), and 8 rRNA genes (four rRNA species). Maximum likelihood phylogenetic analysis yielded a well-resolved tree of the genus Zingiber, and Z. teres and Zingiber mioga were sister species in this tree. The development of DNA barcodes could aid the identification of Zingiber species.

description: Simple, reliable and cost-effective methods for detecting pathogens are a vital part of diagnostics inside and outside the clinic, in particular in the developing world. Paper based colorimetric techniques are a promising approach for biosensors and bioassays as they can be used at the point of sampling and require little equipment. This study reports on the development of a colorimetric cellulose bioassay that can detect pathogen DNA with covalently attached single-stranded DNA probes. Chemical activation of cellulose via tosylation and oxidation was investigated. The successful activation of cellulose was characterised by Fourier transform infrared spectroscopy, scanning electron microscopy and elemental analysis. Sulfhydryl and amine functionalised oligonucleotide probes complementary to a segment of IS6110 element in Mycobacterium tuberculosis genome were covalently immobilised on the cellulose strips for recognition of target nucleic acid. The detection of biotinylated target oligonucleotides was achieved with horseradish peroxidase (HRP) linked to streptavidin that binds biotin with high affinity. HRP catalysed the oxdidation of tetramethylbenzidine by hydrogen peroxide. The successful assay was confirmed by the appearance of blue coloured spots on cellulose strips incubated with biotinylated target oligonucleotides complementary to the surface attached probe. The study also showed that tosylated cellulose is more reliable for the detection of targets. Initial experiments have shown sensitivity upto 0.1 µM and considerable specificity. High probe immobilization efficiencies (>90%) have been observed. The assay was also effectively demonstrated with mycobacterial DNA. Additionally, the development of a label free assay based on a dual-probe approach was investigated, but did not yield conclusive results. The developed assay has the potential for use as a simple test for the detection of pathogen DNA in clinical samples since it requires minimal equipment and is cost effective. In addition, it also shows the potential use of tosylated cellulose as a prospective surface for attaching other types of biomolecules in an active conformation.

description: This study explored newly qualified Clinical Psychologists’ (CPs) experiences of personal professional development (PPD) during doctoral training. In particular there was a focus on their experiences of their personal and professional identities. Within literature relevant to PPD in Clinical Psychology training, personal and professional development were largely conceptualised as separate processes. Yet models of reflective practice would suggest that an awareness of the personal self is necessary for effective clinical work. The research questions were ‘How do newly qualified CPs experience their personal and professional identities during doctoral training? and ‘How do they experience the boundary between their personal and professional development?’. To respond to these questions seven newly qualified CPs were interviewed regarding their experiences of their personal and professional identities during training. A qualitative research design was employed and Interpretative Phenomenological Analysis was used to analyse the data. Three superordinate themes were identified within the data: Developing self-acceptance; Enhancing awareness of self and others; Taking risks and managing uncertainty. Within these results there was a strong message of an inextricable link between personal and professional identities. It seemed that participants started from a position of being themselves, and during training negotiated the dilemmas of learning a professional role. In order to do this they would often look to others for how to negotiate this process. Yet this process could create challenges, as bringing one’s personal self into the professional arena was not always seen as acceptable. If participants were able to show personal aspects of themselves this could make them feel vulnerable and, therefore, these processes held an element of uncertainty. Where participants were able to show their personal selves and felt validated, this allowed for developing self-acceptance. The implications for clinical training and the clients with whom CPs work are discussed.
What Goes Unheard When Struggling Mothers Speak? A Qualitative Study Using the Adult Attachment Interview

Thematic Analysis

description: Studies of attachment in the community suggest that most people have secure attachment styles, but as many as 40% may have an insecure attachment style (Bakermans-Kranenburg & van Ijzendoorn 2009). Frightening parental behaviour has been found to predict disorganised attachment in infants, which in turn is associated with clinical disturbance in adolescence (Van Ijzendoorn, Schuengel & Bakermans-Kranenburg, 1999). Insecure attachment has been found to be disproportionately more common in many psychiatric disorders than the general population: including substance misuse, eating disorders, and Personality Disorder (PD). Transgenerational transmission of attachment has become widely researched over recent years and evidence has shown that a mother’s attachment style can predict the attachment style of her infant (Ward, Ramsay, Turnbull, Steele, Steele, & Treasure, 2001). Research has found that a mothers’ ability to mentalize about her own early attachment relationships has important implications in her transition to becoming a mother. Motherhood can be challenging for mothers who have good mental health, therefore women with poor mental health may find the transition to motherhood especially stressful. The aim of the current study was to give voice to mothers who have been silenced in many ways, to learn from their struggles and to help services develop more effective ways to reach ‘hard to reach’ vulnerable mothers. The Adult Attachment Interview (AAI; George, Kaplan, & Main, 1984) was conducted with eight mothers who were attending a Mentalization-Based Treatment (MBT; Bateman & Fonagy, 2004) group designed for mothers who had caused harm to their children and had subsequently had them removed from their care. Thematic Analysis was used to analyse the AAI transcripts and five main themes emerged: ‘Love and loss’, ‘Change and confusion’, ‘Families and normality’, ‘Safety and boundaries’ and ‘Strength and vulnerability’. The findings contribute to the field of maternal mental health research and clinical implications are discussed at an individual, organisational and societal level.

description: Protonated benzylamine and its N-methylated derivatives, [C6H5CH2NH3−n(CH3)n]+ (n = 0−3), have been adopted as cations in chlorocadmate(II) and chlorocuprate(II) complexes, showing inorganic–organic hybrid architectures. For the Cd(II) compounds, the anionic structures vary from perovskite-type layers (n = 0) to chains (n = 1–3). For Cu(II) compounds, the anionic structures range from perovskite-type layers (n = 0), chains (n = 1) to mononuclear species (n = 2–3). Coordination geometries of the metal ions and intermolecular interactions have been analyzed. Their dielectric properties have been measured.
