How to evaluate metacognitive functioning in psychotherapy? The metacognition assessment scale and its applications
Authors: Semerari Antonio , Carcione Antonino , Dimaggio Giancarlo , Falcone Maurizio , Nicolò Giuseppe , Procacci Michele , Alleva Giorgio 
Published: August 2003

AbstractIn this article the authors present a method and a scale for the evaluation of the metacognitive profiles of psychotherapy patients. There will be a description of the metacognitive function and of the alterations that occur to it during treatment. Various hypotheses will then be considered: (1) that the metacognitive function has a modular structure; (2) that for each type of psychopathological condition there is a different metacognitive deficit profile; (3) that to be successful psychotherapy needs to involve an improvement in any deficient metacognitive sub‐function. There will then be a presentation of the Metacognition Assessment Scale (MAS) for the assessment of metacognitive deficits during psychotherapy. We shall then describe the first results we have on the application of the scale. Finally there will be an analysis of two patients suffering from Personality Disorders and a demonstration of what metacognitive deficit profile each one has and how it is modified over the course of psychotherapy treatment. The article ends with a discussion of the hypotheses made at the start in the light of the results that have emerged. Copyright © 2003 John Wiley & Sons, Ltd.
Change of self‐image in patients with neurotic, borderline and psychotic disturbances
Authors: Granberg Åke , Armelius Kerstin 
Published: August 2003

AbstractChanges in the self‐image of severely disturbed psychiatric patients diagnosed with Kernberg's (1981) structural interview as having neurotic, borderline and psychotic personality organization (NPO, BPO and PPO) were studied in a naturalistic 5‐year follow‐up programme of milieu treatment. Self‐image was measured with Structural Analysis of Social Behavior (Benjamin, 1974) introject ratings. After treatment all patients had changed in the affiliation dimension of the self‐image, while there was almost no change in the interdependence dimension. A more detailed analysis showed that for the NPO and PPO patients the higher overall affiliation was due to a less attacking self‐image, while for the BPO patients it was due to more self‐love. Both at intake and follow‐up the PPO patients' ratings showed a positive self‐image and those of the BPO patients showed high self‐control. These ratings contrast with the diagnostic descriptions of such patients. It is suggested that these differences in perspective might lead to interpersonal problems. Copyright © 2003 John Wiley & Sons, Ltd.

AbstractTreatment of the ligands 1‐(3‐thia‐5‐hydroxypentyl)‐3,5dimethylpyrazole (thpd) and 1‐(3‐thia‐6‐hydroxyhexyl)3,5‐dimethylpyrazole (thhd) with [PdCl2(CH3CN)2], [PtCl2(CH3CN)2], and NiCl2·6H2O produces the complexes [MCl2(L)] [M= Pd, L = thpd (1), thhd (2); M = Pt, L = thpd (3), thhd (4); M = Ni, L = thpd (5), thhd (6)], which have been characterised by elemental analyses, conductivity, IR, electronic spectra, and NMR spectroscopy (when possible). The crystal structures of 2, 3, and 4, determined by single‐crystal X‐ray diffraction, each consist of discrete [MCl2(L)] units. Each MII atom is coordinated by the pyrazolyl nitrogen and the thioether sulfur from the ligand and two cis chloride ions in a square‐planar geometry. Crystallisation of [NiCl2(thpd)] in non‐anhydrous alcohols yields [NiCl(H2O)2(thpd)]Cl ([7]Cl), the crystal structure of which was determined by single‐crystal X‐ray diffraction to reveal nickel atoms coordinated by two water molecules, one chloride ion and one thpd ligand (coordinating via all three donor atoms, N, S, and O) in a skew‐trapezoidal bypyramid (distorted octahedral) geometry.

AbstractThe compounds [Fe(C5H5)(C5H4CH2NMe3)][TCNQ] (1), [Fe(C5H5)(C5H4CH2NMe3)][TCNQ]2.MeCN (2) and [Fe(C5H5)(C5H4CH=CH‐p‐C5H4NMe)][TCNQ] (3) have been obtained from reaction of the corresponding ferrocene iodide and TCNQ or LiTCNQ. Their crystal structures have been determined, showing that 1 and 3 have only mononegative TCNQ radicals forming one‐dimensional stacks. In compound 3 the pyridine substituent also overlaps with the stacked TCNQ. The formation reaction of 2 implies the reduction of neutral TCNQ by the iodide anion; in this reaction the reduction is partial and the formal charge of every TCNQ is approximately 0.5 e− with some degree of electron delocalization. The TCNQs also overlap to form a one‐dimensional stack in the solid. The three compounds are diamagnetic, indicating a strong antiferromagnetic coupling between the TCNQ spins.

AbstractFour mixed‐ligand complexes of [M(mpa)(phen)]n [M = Cd (1) or Zn (2) and mpa = m‐phthalate and phen = 1,10‐phenanthroline) and [M2(mpa)2(2,2′‐bpy)2]n [M = Zn (3) or Cd (4) and 2,2′‐bpy = 2,2′‐bipyridine] have been synthesized and their crystal structures have been established by single‐crystal X‐ray diffraction. They all consist of one‐dimensional ribbons featuring dinuclear units. Both 1 and 2 crystallize isomorphously in the monoclinic space group P2/c and feature helical chains. While 3 and 4 crystallize in the triclinic space group P$\bar 1$
. The one‐dimensional ribbons are assembled into three‐dimensional networks by π−π stacking interactions. They all show strong blue photoluminescence and are stable in air up to ca. 402, 371, 365 and 370 °C, respectively. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)

Authors: Papakyriakou Athanasios , Katsaros Nikos 
Published: August 2003

AbstractThe solution structure of the InIII−bleomycin A2 complex (InBLM) has been determined by NMR studies in combination with molecular modelling. Our data indicate that BLM is coordinated to InIII through five nitrogen ligands in a distorted tetragonal pyramid configuration. The stability and homogeneity of InBLM has allowed us to obtain a well‐defined model of the complex formed at low pH, which is a very potent tumour‐imaging agent. (© Wiley‐VCH Verlag GmbH & Co.

Layered [BaM(C3H2O4)2(H2O)4] (M = Fe or Co) Complexes − Spectroscopic, Magnetic and Thermal Study
Authors: Gil de Muro Izaskun , Lezama Luis , Insausti Maite , Rojo Teófilo 
Published: August 2003

AbstractComplexes with formula [BaM(C3H2O4)2(H2O)4], where M = Fe or Co, were synthesised and characterised. These two types of complexes are isostructural and crystallise in the Pccn space group. Their structure consists of two‐dimensional networks of octahedral MO6 polyhedra in which the transition metal ions are coordinated by bridging malonate ligands, through the O‐C‐O atoms. These M‐malonate units are extended along the crystallographic [101] plane. Spectroscopic data are consistent with the cations being in a high‐spin octahedral symmetry. The two types of compounds exhibit 2D antiferromagnetic interactions as well as weak ferromagnetism below the Néel temperature, as a result of an intralayer misalignment of the spins. Thermal treatment of the metallo‐organic precursors gave rise to BaMO3−y oxides at lower temperatures and reaction times than those found in the literature using the ceramic method.

Published: August 2003

AbstractA series of RhI complexes was prepared and characterised with the following hemilabile amphiphilic phosphanes: R−(C6H4)−(OCH2CH2)n−PPh2 [1 (R = tert‐octyl, n = 1), 2 (R = tert‐octyl, $\bar n$
= 5), 3 (R = tert‐octyl, $\bar n$
= 13), 4 (R = n‐nonyl, $\bar n$
= 1.4), 5 (R = n‐nonyl, $\bar n$
= 5), 6 (R = n‐nonyl, $\bar n$
= 11)]. The reactions between 1−6 and [Rh(COD)(THF)2]+, and the subsequent reaction with CO were studied by 31P NMR and IR spectroscopy. The data are consistent with the formation of P‐coordinated and chelated (P,O) species for ligands 2−6, in agreement with the hemilabile character of these ligands. In the case of ligand 1, the complex trans‐[Rh(1)2(CO)2]+ has been isolated and the cis‐[Rh(1)2(CO)2]+ compound has been detected. [Rh(1)2(CO)]+ was prepared by decarbonylation of trans‐[Rh(1)2(CO)2]+, and low‐temperature NMR spectroscopic studies have shown the hemilabile character of 1 with a very weak P−O interaction. The molecular structure of trans‐Rh(CO)(1)2Cl was determined by X‐ray crystallography and shows that the conformation of the tert‐octylphenoxyethyl chains is nearly identical to that previously reported in the complex trans‐PdCl2(1)2.

Solution Structures of Binary and Ternary Metal Ion Complexes of 9‐(5‐Phosphonopentyl)adenine (3′‐deoxa‐PEEA). A Nucleotide Analogue Related to the Antivirally Active 9‐[2‐(Phosphonomethoxy)ethyl]adenine (PMEA)

AbstractThe acidity constants of the twofold protonated acyclic 9‐(5‐phosphonopentyl)adenine, H2(dPEEA)±, as well as the stability constants of the M(H;dPEEA)+ and M(dPEEA) complexes with the metal ions M2+ = Mg2+, Ca2+, Sr2+, Ba2+, Mn2+, Co2+, Ni2+, Cu2+, Zn2+ or Cd2+, have been determined by potentiometric pH titrations in aqueous solution at I = 0.1 M (NaNO3) and 25 °C. Application of previously determined straight‐line plots of log KM versus pKH for simple phosph(on)ate ligands, R‐PO32−, where R represents a residue which cannot participate in the coordination process, proves that the primary binding site of dPEEA2− is the phosphonate group with all the metal ions studied. However, for the M(dPEEA) systems with Co2+, Ni2+, Cu2+, Zn2+ and Cd2+ a (in part rather small) stability increase is observed which is due to macrochelate formation with the adenine residue, i.e. most likely with N7. The formation degrees of the macrochelates are 17 ± 15%, 28 ± 10%, 46 ± 12%, 42 ± 28%, and 42 ± 9% (3σ), respectively. This means that in this respect dPEEA2− resembles the parent nucleotide adenosine 5′‐monophosphate (AMP2−) more than its chain‐shortened analogue 9‐(4‐phosphonobutyl)adenine (dPMEA2−); indeed, in a first approximation macrochelate formation increases for a given metal ion within the series M(dPMEA) < M(dPEEA) < M(AMP). However, the coordinating properties of all three mentioned ligands differ significantly from those of the antivirally active 9‐[2‐(phosphonomethoxy)ethyl]adenine (PMEA2−) which, due to the presence of an ether oxygen in the aliphatic side chain, has a different coordination chemistry which involves five‐membered chelates with the ether oxygen atom. In addition, the stability constants of the mixed ligand complexes formed between Cu(Arm)2+, where Arm = 2,2′‐bipyridine (Bpy) or 1,10‐phenanthroline (Phen), and the H(dPEEA)− or dPEEA2− species were also measured. Detailed stability constant comparisons reveal that in the monoprotonated ternary Cu(Arm)(H;dPEEA)+ complexes the proton is at the phosphonate group and that stacking between Cu(Arm)2+ and H(dPEEA)− plays a significant role. For the Cu(Arm)(dPEEA) complexes a large increase in complex stability (compared to the stability expected on the basis of the basicity of the phosphonate group) is observed, which is due to intramolecular stack formation between the aromatic ring systems of Phen or Bpy and the purine moiety of dPEEA2−. The formation degree of the stacked isomers is in the order of 65 to 80%. Comparisons of the Cu(Arm)(PA) systems, where PA2− = dPEEA2−, dPMEA2− or AMP2−, reveal that here dPEEA2− resembles its parent AMP2− less closely than dPMEA2− does. The biological implications of these results, including antiviral activities, are shortly discussed. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
Mechanistic Insight Gained into the Ligand Substitution Reactions of Bis(o‐benzosemiquinonediiminato)(triphenylphosphane)cobalt(III) − Kinetic, Solvent, and Volume Profile Studies

AbstractThe ligand substitution reactions of bis(o‐benzosemiquinonediiminato)(triphenylphosphane)cobalt(III), [CoIII(s‐BQDI)2(Ph3P)]+, were studied with imidazole (Imid) and 4‐dimethylaminopyridine (4‐Me2Npy) as entering nucleophiles in MeOH and CH3CN as solvents (S). The complex [CoIII(s‐BQDI)2(Ph3P)S]+ undergoes dissociation of the solvent to form a five‐coordinate intermediate, [CoIII(s‐BQDI)2(Ph3P)]+, which binds the entering nucleophile in a rate‐determining step through a six‐coordinate transition state, [CoIII(s‐BQDI)2(Ph3P)L]+, followed by the release of triphenylphosphane to form [CoIII(s‐BQDI)2L]+. From the temperature and pressure dependence of the substitution of triphenylphosphane by imidazole, the activation parameters for the forward and reverse reactions of [CoIII(s‐BQDI)2(Ph3P)]+ with imidazole in MeOH were found to be ΔH‡ = 58±2 and 43.4±0.5 kJ·mol−1, ΔS‡ = −116±6 and −73±2 J·K−1·mol−1, and ΔV‡ = −10.6±0.1 and −8.7±0.3 cm3·mol−1, respectively. In CH3CN, however, ΔH‡, ΔS‡, and ΔV‡ for the forward reaction were found to be 50±3 kJ·mol−1, −111±9 J·mol−1·K−1, and −12.9±0.3 cm3·mol−1, respectively. The activation parameters for the reaction between [CoIII(s‐BQDI)2(Ph3P)]+ and 4‐dimethylaminopyridine in MeOH for the forward and reverse reactions were found to be ΔH‡ = 76±2 and 47.9±0.4 kJ·mol−1, ΔS‡ = −51±7 and −64±2 J·K−1·mol−1, and ΔV‡ = −10.5±0.3 and −11.1±0.2 cm3·mol−1, respectively. From these reported rate and activation parameters, the substitution of triphenylphosphane by imidazole and 4‐dimethylaminopyridine follows an associative mechanism. The ligand substitution reactions of [CoIII(s‐BQDI)2(Ph3P)]+ in CH3CN were found to be faster than those in MeOH, which is attributed to the potential for hydrogen bond formation with the entering nucleophile in the case of MeOH as solvent.

AbstractDTPA‐bisamide derivatives with alkyl chains containing 14, 16 and 18 carbon atoms were synthesized and complexes of various trivalent lanthanide ions (Ln = Gd, La, Pr, Eu) were formed. Variable temperature proton NMR spectroscopy of paramagnetic praseodymium(III) and europium(III) complexes revealed that long aliphatic substituents considerably increase the energy barrier for the intramolecular rearrangement around the lanthanide ion. The gadolinium(III) complexes were incorporated into mixed micelles, and photon correlation spectroscopy showed that the mean sizes of all the micelles were within the same range. The NMRD curves of all three DTPA‐bisamide‐gadolinium complexes incorporated in mixed micelles display higher relaxivity values than the commercially available Gd−DTPA contrast agent. The higher relaxivity obtained for the micellar DTPA‐bisamide‐gadolinium complexes with C14 and C16 chains relative to the micellar DTPA‐bisamide‐GdIII C18 chain complex could be attributable to the fact that the alkyl chain containing 18 carbon atoms is longer than the alkyl chain of the major component of the micelles, DPPC, in which it is inserted. This would allow increased mobility of the polar head and hence a lower relaxivity. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)

Published: August 2003

AbstractThe study of reaction mechanisms by NMR spectroscopy normally suffers from limitations in sensitivity that result in substantial difficulties in the detection and characterisation of reaction intermediates. One technique that can circumvent this problem is the use of para‐enriched hydrogen. Here, an overview of the developments in the study of chemical reactions using parahydrogen‐assisted NMR spectroscopy is presented, with the characterisation of a number of new hydride complexes of iridium, rhodium, ruthenium and tantalum being described. A number of studies involving transition metal clusters and catalytic applications are also considered. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)

AbstractTwo compositions in the La‐Ba‐Cu‐Co‐O system − La2Ba3Cu2Co3O13 and La2Ba3Cu3Co2O13 − have been synthesized and characterized by means of SAED (Selected Area Electron Diffraction) and HREM (High Resolution Electron Microscopy). The La2Ba3Cu2Co3O13 phase leads to a fivefold perovskite superstructure along the c axis, which can be described as formed by the recurrent intergrowth of the two alternating blocks ···PP··· and ···POhP··· (P = pyramid and Oh = octahedron). Pyramidal and octahedral sites are randomly occupied by Cu/Co cations, while La/Ba cations exhibit an ordered distribution. The La2Ba3Cu3Co2O13 composition gives rise to a mixture of phases in which a new phase showing a threefold superstructure due to the sequence ···POhP··· coexists with a fivefold superstructure with the same polyhedra sequence (···PPPOhP···) as the previous one, but a disordered arrangement of lanthanum‐barium cations.

Published: August 2003

AbstractThe reactions of [LiAl(PH2)4] or [NaAl(PH2)4] with Et2SiCl2 or iPr2SiCl2 yield the dialkyldiphosphanylsilanes Et2Si(PH2)2 (1) and iPr2Si(PH2)2 (2), respectively. Both compounds were identified by NMR spectroscopy as well as mass spectrometry. Compound 2 reacts with MEt3 (M = Al, Ga, In) to form the cage compounds [iPr2Si{P(H)MEt2}2]2 (3: M = Al, 4: M = Ga, 5: M = In). These three clusters were fully characterised by NMR and IR spectroscopy as well as by single‐crystal X‐ray diffraction. The central structural motif of 3−5 is an adamantane‐like cage composed of four metal, four phosphorus and two silicon atoms. They are the first ternary clusters with these combinations of elements and crystallise isotypical in the triclinic space group P$\bar 1$

AbstractThe reaction of AgPF6 and cis,cis‐1,3,5‐triaminocyclohexane (TACH) in a 1:1 ratio in methanol solution gave two different coordination polymer crystals depending on the presence/absence of water. The crystal structure in the absence of water is a one‐dimensional, tube‐like polymer with formula {[AgI(TACH)]PF6}n, while in the presence of water the structure is a three‐dimensionally expanded complex network built up from cage units containing a water molecule, {[AgI3(TACH)4](PF6)3·H2O}n; this structure is induced even by a trace amount of water.

Redox Chemistry of Actinide Ions in Wells−Dawson Heteropolyoxoanion Complexes
Authors: Chiang Ming‐Hsi , Soderholm L. , Antonio Mark R. 
Published: August 2003

AbstractThe redox behavior has been characterized for several actinide (An) complexes with the monovacant Wells−Dawson anion, of the form [Ann+(α‐2‐P2W17O61)2]n−20 (An = Th4+, U4+, Np4+, Pu4+, and Am3+). Two complexes, with An = U4+ and Am3+, show redox activity under oxidizing conditions, which is attributed to the actinide oxidation. Am3+ is oxidized to Am4+ with an E1/2 = +1.21±0.01 V, and U4+ oxidizes to U5+ with a measured E1/2 = +0.55±0.01 V vs. Ag/AgCl. Although the cyclic voltammetry (CV) data are consistent with a reversible redox couple, bulk oxidative electrolysis of [U4+(α‐2‐P2W17O61)2]16− results in the decomposition of this complex to produce uranyl acetate and the free monovacant Wells−Dawson anion. In contrast, all of the CV data from the actinide coordination complexes differ from equivalent data obtained from the [α‐2‐P2W17O61]10− ligand itself. There are two complexed An4+ ions, Np and Pu, that undergo reduction over the same potential range as the ligands themselves. In situ X‐ray spectroelectrochemistry is used to quantify the actinide response. The Np4+/Np3+ redox behavior is a classically single ion process, with a formal potential of −0.84±0.01 V that was determined from a Nernst plot of X‐ray absorption near‐edge structure (XANES) data. The Pu4+/Pu3+ formal reduction potential in the complex [Pu(α‐2‐P2W17O61)2]n− was determined to be −0.17±0.01 V using the same methodology. However, in this latter case, the slope of the Nernst plot indicates that 0.72±0.03 electrons are involved in the reduction. This is a significant deviation from the 1 electron expected for the Pu couple, and is discussed in terms of the concomitant reduction of the P−W−O framework of the Wells−Dawson anion.
