Authors: Steudel Ralf , Strauss Reinhard 
Published: February 2015

Abstract
Cyclooctasulfur, S8, dissolved in CS2 reacts at 130-155 °C in sealed ampoules to give S6 and S7 whose concentrations have been determined by HPLC. The half-time of the reaction is independent of the initial S8 concentration and decreases from 232 min at 130 °C to 64 min at 150 °C. After long reaction times equilibrium concentrations are observed which are in agreement with the law of mass action. From the temperature dependence of the equilibrium constants the following reaction enthalpies (at 130-155 °C) have been calculated:
3/4S8⇌S6 ⊿H°=24kJ/mol
7/8S8⇌S7 ⊿H°=21kJ/mol

On Some Ternary Phases in the Systems Nb-Zn-Al and Ta-Zn-Al
Authors: Drašner A. , Blažina Ž. 
Published: February 2015

Abstract
In the systems NbZn2-xALx and TaZn2-xAlx a great number of samples was prepared and investigated by means of X-ray powder diffraction. In both systems at the equiatomic composition two new ternary phases were found. Their crystal structures were determined and found to belong to the Friauf-Laves type (MgZn2 prototype, S. G. P 63/mmc). The unit cell parameters of NbZnAl are a = 506.4 ± 0.2 pm, c = 829.9 ± 0.8 pm, c/a = 1.639, and for TaZnAl a = 503.8 ± 0.2 pm, c = 827.9 ± 0.3 pm, c/a= 1.643. In the system NbZn2-x-Alx, at the composition NbZn1.25Al0.75, a ternary phase of the AuCu3 structure (a= 394.4 i 0.3 pm, S. G. Pm3m) was also observed, while in the system NbZn3-xAlx a single phase region, having the AuCu3 structure, was found to exist up to the composition NbZ2Al. The stability of these Friauf-Laves phases and those found previously in the systems ZrZn2-xAlx and HfZn2-xAlx is discussed in terms of atomic sizes and valence electron concentration.

The tridentate mono-basic Schiff base N-(2-diethylaminoethyl)salicylaldimine ≙Hsal-en-NEt2 forms complexes 1 = [(sal-en-NEt2)MY] with divalent metals M (Y = halide). The preparation of three copper(II) complexes 1a (Y=Br), 1b (Y=Cl), and 1c (Y=SCN) and one palladium(II) complex 1(1 (Y=Cl) is described and the UV/VIS spectra of these complexes in methanol and chloroform are compared and discussed. The crystals of 1a · CHCl3, 1b · CHCl3, and 1d · CHCl3 are all isotypic and crystallize in the orthorhombic space group Pbca, whereas the solvent-free crystals of 1 b (and also 1 a) are monoclinic with the space group P21/c. The metal is 4-coordinate with an almost planar ONNY donor atom arrangement around the palladium and with a distorted arrangement around the copper. The crystals consist of separate non-bridged complex units and the chloroform is not coordinated.

Published: February 2015

Abstract
The stereochemistry of the photo reaction products of tricarbonyl-η-6,6-dimethyl-fulvene-chromium(O) (1) with 7-methyl-and 7-methoxycycloheptatriene was studied by NMR-spectroscopy. Both trienes add to 1, displace a CO ligand, and form substituted dicarbonyl-η3-2-cycloheptadienylene-η5-2-cyclopentadienylidene-propane-chromium(0) complexes. With C7H7CH3 only one isomer (3) is formed with the methyl-group in endo-position and the enyl system encompassing C(1′)-C(3′) of the seven membered ring. C7H7OCH3 yields 3 isomers which were separated by column chromatography. 5 has the same constitution as 3. The isomers 4 and 5 bear the OCH3-group in e^o-position. The enyl system of 4 is located on C(1′)-C(3′), that of 6 on C(3′)-C(5′). 6 rearranges at room temperature to 4.
Synthese und Kristallstrukturen einiger Tetramethylstibonium-Hydrogendicarboxylate / Synthesis and Crystal Structures of Some Tetramethylstibonium Hydrogendicarboxylates
Authors: Milewski-Mahrla Beatrix , Schmidbaur Hubert 
Published: February 2015

Reactions of pentamethylantimony (CH3)5Sb with carboxylic acids in the molar ratio 1:2 afford one equivalent of methane and essentially quantitative yields of crystalline tetramothylstibonium hydrogendicarboxylates. Six new compounds of this series have been synthesized using benzoic, o-phthalic, salicylic, 4-ethoxy-salicylic, oxalic, and malic acid, and characterized by analytical and spectroscopic data. An ionic structure with strong hydrogen bonds in the anionic components is proposed.
The crystal structures of the hydrogen-dibenzoato (1), hydrogen-ortho-plithalato (2) and 4-ethoxy-hydrogen-salicylate (3) were determined by single crystal X-ray diffraction. The compounds can be described as having ionic lattices with some donor-acceptor inter­actions between the stibonium centers and the carboxylate oxygen atoms. The anions are characterized by strong hydrogen bonds O...H...O. Thus, the (CH3)4Sb-tetrahedron in 1 is distorted by two benzoate oxygon atoms (at 304(2) and 340(2) pin). The cation in 2 is largely undistorted and the anion has a hydrogenphthalate hydrogen bond of d(O...H...O) = 232 pm. The cation-anion contact in 3 is as short as d(Sb-O) = 289 pm rendering the Sb atom pentacoordinate.

The 31P NMR spectra of PCl3=N[PCl2 = N]nPCl2=S (n = O-2) undergo significant changes in ν/2 and 4JPP when the temperature is lowered. The effects are discussed in terms of T1 relaxation effects which may re­flect the mobility of phosphorus in compounds 1-3.
Bei 31P-NMR-Untersuchungen an linearen Phosphorylphosphazenon der allgemeinen Struk­tur PCl3=N[PCl2=N]nPCl2=O (n=O-3) ha­ben wir eine höchst augenfällige Abhängigkeit der Parameter Kopplungskonstante, chemische Verschiebung und Halbwertsbreito ν/2 von Lö­sungsmittel und Temperatur festgestellt [1]. Die Änderungen von ν/2 betroffen dabei vor allem die ondständige PCls-Gruppo. Es konnte gezeigt werden, daß dieser Effekt wahrschein­lich durch Relaxation über den Spinrotations- Mechanismus (T1SR) zustande kommt. Um weiteres Untersuchungsmaterial in die Hände zu bekommen und um damit zu erkennen, in wel­chen Grenzen die beschriebenen Effekte auftreten, wurden nun auch die entsprechenden Thioanaloga in die Untersuchungen mit einbe­zogen.

Abstract
Na6CoS4 crystallizes in the hexagonal space group P 63mc with a = 890.9(2) pm and c = 687.8(2) pm, Z = 2. The crystal structure was determined from four circle diffractometer data and refined to a conventional R-value of 0.020. Na6CoS4 is isotypic with Na6ZnO4. The crystal structure can be derived from a h.c.p. arrangement of S atoms. Co atoms occupy tetrahedral voids, the resulting CoS4-tetrahedra being almost regular with an average Co-S distance of 235 pm. Na atoms occupy tetrahedral and octahedral voids in the ratio 1:1.

Abstract
{[Cu3(3′-GMP)2(3′-GMPH)2(H2O)5]·7H2O}n (1) was isolated from an aqueous solution of Cu(NO3)2 and guanosine 3′-monophosphate at a pH of 4.4. 1 is monoclinic space group C 2 with a = 29.140(7), b = 6.865(5), c = 16.980(7) Å, β = 90.31(3)°, Z = 2, Dc = 1.81 g·cm-3. The structure was refined to R - 0.065 with i?w = 0.060 for 2642 independent reflections. It is disordered about a crystallographic diad axis with one of the copper atoms Cu(2) sited on this axis. This and the other independent copper atom Cu(l) both display square pyramidal geometries. Cu(l) binds N(7) of a guanine base, two phosphate O atoms of nucleotide molecules not symmetry-related to one another and two water oxygens. The guanine base involved in this coordination adopts a syn-conformation relative to the ribose ring with χCN= -118.5°. Cu(2) is coordinated by four phosphate O atoms of different nucleotide molecules and one water oxygen. The second guanine base, which is not involved in metal binding, displays the anti-conformation relative to the ribose ring.

Authors: Zimmer Hans , Jayawant Madhusudan , Amer Adel , Ault Bruce S. 
Published: February 2015

Abstract
Alkylamino-and cycloalkylaminotriphenylphosphonium halides react with elemental halogens or interhalogen compounds to afford alkylamino-or cycloalkylaminotriphenyl-phosphonium trihalides. The stability of these trihalides depends on the cation as well as the trihalide anion. The assignment of a trihalide structure to these compounds was based on elemental analysis and on IR-and Raman spectroscopic evidence. Most stable are the tribromide and [IX2]⊖ salts. During all reactions involving N-alkylamino-and N-cyclo-alkylaminotriphenylphosphonium halides and elemental halogens an N-halogenation of the cation was not observed.

Abstract
The tetraalkyldibismutanes R2BiBiR2 (R = Et, Pr, iPr, Bu) were synthesized by reactions of 1,2-dibromoethane with sodium dialkylbismutides, which were produced by cleavage of the corresponding trialkylbismutanes with sodium in liquid ammonia. The dibismutanes were isolated in good yields as air sensitive red liquids. Spectral data of dibismutanes and some bismutanes are compared with data of their antimony analogues. 1H NMR spectra reveal, that the methylene protons in Et4Bi2 as well as the methyl groups in iPr4Bi2 are diastereotopic.

Abstract
The system TlI-Tl2Se was investigated by DTA, X-ray and metallographic methods. At the Tl2Se corner of the system a solid solution up to 25 mol% TlI is observed, which decomposes peritectically at 681 K. Two new compounds Tl5ISe2 and Tl6I4Se were found. The latter is isotypic to a class of compounds found in the TlX-TI2S systems [2]. The crystal structure of Tl6Cl4S was determined. It is based on the TlCl structure (CsCl-type) in which 1/5 of the Tl or Cl atoms, resp., are substituted by Tl2S in a regular manner. The coordination of the anions (Cl, S) is very similar to the coordination of Cl in TlCl or S in Tl2S resp.

Abstract
The crystal and molecular structures of triethylammonium tetrachloroantimonate(III) (1) and tris[methylammonium] hexachloroantimonate(III) (2) were determined by X-ray analysis. In compound 1, SbCl3 molecules are bridged by Cl ions to form chains. The coordination of Sb by Cl atoms yields a distorted tetragonal-pyramidal structure. In compound 2 there are chains of SbCL4
- ions, again through bridging by Cl ions. One Cl ion has no contacts to Sb. The cations of 1 and 2 form hydrogen bonds with the anionic components.
