 Title    Die Struktur des 2  
 Abstract    One of the diastereomeres of 2,3,4,6,7,8-hexamethyl-2,3,4,6,7,8-hexaphosphabicyclo-[3,3,0]octane (PMe)öC2H2 crystallizes in the space group P2i/n with four molecules per unit cell. Two independent molecules are nearly identical in shape but differ by inter-molecular packing. The five-membered rings have a skew chair conformation with all exocyclic methyl groups in axial positions leading to a staggered all-trans conformation of the bicyclic system. The mean bond lengths are P-P = 220.9 pm, P-C = 185.9 pm and C-C = 151.9 pm.

 Title    Cyclische Diazastannylene, DI 1 Die Kristall-und Molekülstruktur der monoklinen Phase von 1.3-Di-feri-butyl-2.2-dimethyl-1.3.2.4A 2 -diazasilastannetidin The Crystal and Molecular Structure of the Monoclinic Phase of l,3-Di-feri-butyl-2,2-dimethyl-l,3,2,4A 2 -diazasilastannetidine  
 Abstract    The crystal and molecular structure of the monoclinic phase of l,3-di-£eri-butyl-2,2-dimethyl-l,3,2,4A 2 -diazasilastannetidine has been determined from three-dimensional X-ray data collected on a two-circle diffractometer at —120 °C (MoKa radiation, 2623 re-flexions, R — 0,050). The crystals are monoclinic, space group C 2/c, with cell dimensions a = 10.655(5), b = 25.75(1), c = 17.33(1) A, ß = 106.8(1)° and Z = 12. Four monomeric (crystal site symmetry 2 (C2)) and four dimeric units (crystal site symmetry I (Cj)) are present in the structure interacting over tin-tin (3.68 A). Remarkable are the very short Sn-N bond (2.09 A) in the monomer and the donation bond Sn-N (2.39 Ä) in the dimer. The coordination of the tin atoms in the different units is discussed in detail.

 Title    Cyclische Diazastannylene, VIII [1] Die Kristall-und Molekülstruktur eines Iminostannylens: Sn3 (NC(CH3 )3 )4 H2 Cyclic Diazastannylenes, VIII [1] The Crystal and Molecular Structure of an Iminostannylene: Sn3(NC(CH3)3)4H2  
 Abstract    The crystal and molecular structure of the compound Sn3(NC(CH3)3)4H2 has been determined from X-ray data (R = 0.044). The crystals are cubic, space group Pa3, with cell dimension a — 1713.6(8) pm and Z = 8. The molecules, which have a seco-norcubane like Sn3N4 framework, are statistically disordered, thus forming closed packed pairs of molecules. The Sn3N4 cage deviates strongly from a cube, the bond angles at Sn approach-ing 80°, and at N 100°. The averaged Sn-N bond distance is 223(1) pm.

 Abstract    Semicobaltates (Co-1/2) containing olefin and trimethylphosphane ligands are synthe-sized from Co(olefin)(PMe3)3 and potassium metal. The X-ray crystal structure determina-tion of the title compound shows that the unit cell contains two K atoms in equal ionic contact with the ethylene ligands of four Co(C2H4)(PMe3)3 complex units, two of which are interacting with both K atoms. In solution the semicobaltates exist in hydrocarbon solvents under argon only, while in contrast under ethylene or nitrogen atmospheres or in donor solvents disproportionation occurs to give Co(O) and Co(-I) species.

 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    Element—Element-Bindungen, IV [1] Molekül-und Kristallstruktur des Tetramethyldiphosphans und -diarsans Element—Element Bonds, IV [1] Molecular and Crystal Structure of Tetramethyldiphosphane and -diarsane  
 Abstract    The molecular and crystal structures of the isotypic compounds tetramethyldiphosphane 1 and -diarsane 2 have been determined by single crystal X-ray diffraction (monoclinic; C2/m; Z = 2; 1/2: -155/-144 °C\a = 540.6(2)/555.8(2); b = 1131.0(6)/l 136.7(6); c -602.5(2)/612.8(2) pm;/? = 97.31(3)/95.24(3)°;P-P 221.2(1)/As-As 242.9(1) pm). In accordance with the crystallographically imposed symmetry 2/m, the molecules adopt antiperiplanar conformation. Their crystal structures are closely related to those of the homologues tetramethyldistibane 3 [1] and -dibismuthane 4 [3]. As found for the latter compounds, the E —E units (E = P, As) are also aligned in linear chains, but the intermolecular E---E contacts (P-P 381/As---As 370 pm) do not allow any extended interaction between molecules, which otherwise would result in thermochromic effects.

 Title    Correlation of Mössbauer Quadrupole Splitting ( zI/?q) and Infrared Cyanide Frequency Separation in Alkali Metal Ferricyanides  
 Abstract    Mössbauer and infrared spectra of the alkali metal ferricyanides M* [Fe(CN)6] • n H 20 , where M1 = H , Li and N a were studied at room temperature. All the three compounds displayed a doublet with small quadrupole splitting (AEq). Infrared spectra of these compounds in solid state gave two frequencies for C = N stretching vibrations with their separation (Av) in increasing order which was found to be linearly correlated with AEq. A plausible explanation has been given in terms of the interaction of Li+ and Na+ cations w ith the CN-ligands of octahedrally symmetric ferricyanide anion [Fe(CN)6] 3-similar to that of hydrogen atoms which are hydrogen bonded in H 3Fe(CN)6.

 Title    Synthese, Basenaddition und Fragmentierung der 1.3.2-Dioxaborolan-4-one Synthesis, Addition of Bases, and Fragmentation of l,3,2-Dioxaborolane-4-ones  
 Abstract    2,5,5-Triorgano-l,3,2-dioxaborolane-4-ones RB(-O-CO-CXY-O-) (2-6) can be prepared from a-hydroxycarboxylic acids XYC(OH)-COOH and dihalogenoorganoboranes RBHal2. They are much weaker Lewis acids than the 2-organo-l,3,2-dioxaborolane-4,5-diones RB(-O-CO-CO-O-) (1). The compounds 1 give 1:1 adducts with the bases DINO, MANO, PyO, and PSy, respectively; the crystal structure determination of If • DINO reveals a simple BO-coordination between the components. On electron impact, the chief fragmen-tation path is the elimination of C02 from compounds 1-6. The thermal degradation of 2-6 seems to be rather complicated in the liquid phase but is unique in the gaseous phase forming the compounds (RBO)3, CO, and XYC = 0.

 Abstract    The organocyclotriarsane, CH3C(CH2As)3 (1), reacts with chromium hexacarbonyl on ultraviolet irradiation to give the complex CH3C(CH2As)3Cr(CO)5 (2), in which the cyclo-triarsane is behaving as a monodentate ligand. The crystal structure of 2 has been determinated by X-ray diffraction. The monoclinic unit cell (space group P2i/n) contains 4 isolated molecules in a hexagonal closest packing. The mass spectrum of 2 shows the parent peak and clear fragmentation patterns. The infrared and Raman spectra are reported for 1 and 2 in the 3000-30 cm -1 region. Most of the fundamental vibrations are assigned.

 Abstract    The crystalline black polymeric Cui complex CuBr • S4N4 can be prepared in high yield from Cu(NÜ3)2 • 3 HoO, NH4Br and S4N4 in methanol. An X-ray structure analysis shows that it is isostructural with CuCl • S4N4. The crystals contain [CuBr]^ chains and the Cu atoms of adjacent chains are bridged by S4N4 groups. The Cu atoms have an almost tetrahedral coordination. Tho l,3-N,N'-bonded S4N4 group has the same conformation and, within narrow limits, the same dimensions as free S4N4. Thermolysis of CuBr • S4N4 at 180 C C yields among other products CuBr, S4N4, and S2N2.

 Title    Übergangsmetall-Carben-Komplexe, CXXVI [1] Darstellung und Struktur symmetrischer Hydroxycarben-Anhydrid-Komplexe des Mangans und Rheniums Transition Metal Carbene Complexes, CXXVI [1] Preparation and Structure of Symmetrica! Hydroxycarbene Anhydride Complexes of Manganese and Rhenium  
 Abstract    Symmetrical anhydrides of hydroxycarbene complexes of manganese and rhenium, [JT-C5H5(C0)2MC(R)]20, (M = Mn, Re) are prepared by reaction of cationic carbyne com-plexes [.T-C5HÖ(CO)2MCR]BX4 with the corresponding metal carbonyl acylates Li[7r-C5H5(C0)2MC(0)R]. [^-C5H5(CO)2MnC(C6H5)]20 is also obtained by controlled hydrolysis of Tr-CsH^CO^MnCXBrJCeHs. The new complexes are characterized spectro-scopically and by an X-ray structure analysis of [jr-CsH^CO^MnQCeHs^O. Bei der Reaktion von Pentacarbonyldiethyl-aminocarbin-chrom-tetrafluorborat, [(CO)5CrCNEt2]BF4, mit NMe4[(C0)5MC(0)R] (M = Cr, W) entstehen die gemischten Hydroxy-carben-Anhydrid-Komplexe
