 Title    Molekülstruktureii, Schwingungsspektren und Konformation der Thiooxalsäurederivate CH3S-CO-CONH2, CH3S-CS-CONH2, C2H50-C0-CSNH2 und K[OSC-CONH2] Molecular Structure, Vibrational Spectra and Conformation of the Thiooxalic Acid Derivatives CH3S-CO-CONH2, CH3S-CS-CONH2, C2H50-C0-CSNH2 and K[OSC-CONH2]  
 Abstract    The crystal structures ofCH3S-CO-CONH2 (1), CH3S-CS-CONH2 (2), C2H50-C0-CSNH2 (3) and K[OSC-CONH2] (4) have been determined by single crystal X-ray diffraction. The molecules 1, 2 and 3 are nearly planar and form centrosymmetric dimers by N H • • • O or N-H--S hydrogen bonds with the amidic oxygen or sulfur atom as acceptor atoms. The anion of 4 is not quite planar. The torsional angle around the C-C bond is 18.4°. The con-formations of the title compounds are E, Z' (1 and 2), Z, Z' (3) and Z (4). According to the vibrational spectra, which are discussed briefly, 1 and 3 retain their conformation also in solution.

 Title    On the Central Role of Sulfur in Multi Metal Aggregates with Different Electron Populations: [S2WS2CoS2WS2]' 1 - (n -2, 3)  
 Abstract    The hetero metal sulfur aggregates [Co(WS4)2] n ~ (with variable electron popula-tion: n = 2, 3) could be isolated as salts and characterized by physical measurements (in-cluding X-ray structure analysis). Experimental and theoretical investigations show that due to a strong metal -> ligand electron delocalisation WS4 2-(like M0S4 2 -) is a non-innocent ligand and that the additional charge upon reduction is located mainly at the S atoms of the ligand system.

 Title    X-Ray Structural Analyses of Cyclodecasulfur (S10) and of a Cyclohexasulfur-Cyclodecasulfur Molecular Addition Compound (S6 * S10) [1]  
 Abstract    Low temperature X-ray structural analyses of monoclinic single crystals of Sio and Sö • Sio (prepared from the components) show that the cyclic Sio molecule exhibits the same D2 conformation in both compounds with bond distances between 203.3 and 208.0pm, bond angles (a) between 103 and 111°, and torsional angles (r) between 73 and 124°. The Sß molecule (site symmetry Ci) in Sö • Sio is very similar to the one in pure Sö (dss = 206.2 pm, a= 103°, r = 74°). All intermolecular interactions are of van-der-Waals type. The Raman spectrum of S6 • Sio can be explained by a superposition of the Se and Sio spectra.

 Title    Triphenylstanny]tris(trimethylphosphan)cobalt - Molekül struktur und Eigenschaften Triphenylstannyltris(trimethylphosphane)cobalt -Molecular Structure and Properties  
 Abstract    Potassium cobaltates K+CoLsL' -(L = MeaP, L' = N2, olefin) react with SnCl(CeHs^ or GeBr(CeH5)3 to give tetracoordinate complexes containing Co-Sn and Co-Ge bonds. Crystal and molecular structures of two single crystals were determined. They show tetrahedral molecules Co[Sn(C6Hs)3][P(CH3)3]3 in different packing order. Both tetra-coordinate compounds take up small ligands thereby completing their 18-electron valence shells in compounds Co[E(C6H5)3]L3L' (L = (CH3)3P; E = Ge, L' = CO; E = Sn, L' = CO, C2H4). A sparingly soluble paramagnetic adduct Co[Sn(C6Hs)3]L4 is believed to contain a tin-bonded phosphane. Allgemeines

 Title    Cyclische Diazastannylene, XVIII [1] Zur Frage der Bindungsbeschreibung in Polyedern des Typs Sn4X3Y: Die Kristall-und Molekülstrukturen von Sn4(N Bu)4 und Sn4(N'Bu)30 Cyclic Diazastannylenes, XVIII [1] Bonding Description in Polyhedra of the Sn4X3Y-Type: The Crystal and Molecular Structures of Sn4(N'Bu)4 and Sn4(N<Bu)30  
 Abstract    Crystals of Sn4(N J Bu)4 (1) are monoclinic, space group P2i/c, with cell constants a = 1038.9(4), b = 1468.3(5), c = 1698.8(5) pm, ß = 91.6(1)° and Z = 4, while those of Sn4(N i Bu)30 (2) are triclinic, space group P I, with dimensions a = 1293.0(5), b = 1027.1(5), c = 1716.7(9) pm, a = 90.9(1), ß = 102.5(1), y = 107.0(1)° and Z = 4. The molecules 1 are held together by van-der-Waals forces, whereas two molecules 2 interact in the crystal by weak 0->-Sn donor bonds (290-332 pm) forming dimers. The outstanding structural elements of 1 and 2 are the Sn4N4 and Sn4N30 polyhedra, which can be described by two interpenetrating tetrahedra of tin atoms and of nitrogen or nitrogen and oxygen atoms forming a distorted cube, which approaches "43 m symmetry in the case of 1 and 3m for 2. Characteristic distances are in 1: Sn-N 220.2 pm, in 2: Sn-N 221.3 pm and Sn-0 213.2 pm. An almost ionic bonding model and two covalent models are discussed on the basis of the structural data including Sn4(N i Bu)3OAlMe3.
