 Title    P(C6H5)4[VOBr4]: Synthese, IR-Spektrum und Kristallstruktur P(C6H5)4[VOBr4]: Synthesis, IR Spectrum and Crystal Structure  
 Abstract    PPh 4 [VOBr4] was prepared by the reaction of PPh4Br with VOBr3 in CH2Br2 solu-tion. The structure of the dark violet crystals was determined with X-ray diffraction. PPli4[VOBr4] crystallizes in the space group P4/n with the lattice constants a = 1275.9 and c = 784.5 pm with two formula units per unit cell. The structure type corresponds to the frequently encountered AsPh4[RuNCl4] type. The VOBr4~ ion forms a square pyramid; the V = O bond has a length of 155 pm. In the IR spectrum, the V —O stretching vibration appears at 922 cm -1 .

 Title    Diazadiphosphetidine Platinum(O) Complexes  
 Abstract    The reaction of Pt(COD)2 with cw-[RPNCR3]2 (1), R = CH3, affords the two-coordinate platinum(O) complex PtLo (2) (L = diazadiphosphetidine 1). In benzene solution PtL2, Pt2L3 (3) and L are in equilibrium. 2 and diphenylacetylene or fumaric acid dinitrile give the platinum diazadiphosphetidine complexes LoPt(PhCCPh) (4) and L2Pt[H(NC)CC(CN)H] (5), L = 1.

 Title    Ein- und zweikernige Palladiumkomplexe mit CS2 und PR3CS2 als Liganden [1] Mono-and Binuclear Palladium Complexes with CS2 and PR3CS2 as Ligands [1]  
 Abstract    The compounds Pd(PPr*3)" (n = 2 or 3) and Pd(PMePh2)4 react with CS2 to give the mononuclear complexes (PR3)2Pd(>/ 2 -CS2). In the reactions of Pd(PMe3)4 and Pd(PMe2Ph)4 with CS2 binuclear complexes [(PR3)Pcl(S2CPR3)]2 containing bridging phosphoniodithio-carboxylates as ligands are formed. [(PMe3)Pd(S 2 CPMe3)]o is also obtained from (PR3)2Pd(r? 2 -CS2) (PR3 = PPr'3, PMePho, PPI13) and PMe3. The reactions of Pd(PR3)" with the zwitter ions PMe3CS2 and PMe2PhCS2 lead to binuclear compounds f(PR3)Pd(S2CPR'3)]2 (PR3 = PPI 4 3, PMeoPh, PMePho, PPh3; PR'3 = PMe3, and PK3 = PMePh2; PR'3 = PMe2Ph). [(PMe3)Pd(S2CPMe3)]2 reacts with PMe3 with cleavage of the phosphoniodithiocarboxylate bridges to give (PMe3)2Pd(S 2 CPMe3). The formation of [(PMe3)Ni(S2CPMe3)]2 from Ni(PMe3)4 and PMe3CS2 is also described.

 Abstract    Complexes of the type [L2IrR] (L = butadiene, isoprene, piperylene, 1,4-and 2,3-dimethylbutadiene; R = CH3, CeHs) have been synthesized by reactions of [L2IrCl] with LiR in hexane. With L = 2,3-dimethylbutadiene, [L2IrR] compounds with higher alkyl groups R (e.g. n-C3H7, n-CjHg) can be obtained which for steric reasons are inert against ^-elimination. Th© system [L2IrCl]/L/LiAlH4 (L = 2,3-dimethylbutadiene) yields [L2IrR] with R = 2,3-dimethylbutene-2-yl. The complexes were characterized by NMR and mass spectra.

 Title    Eine neue Synthese, das Schwingungsspektrum und die Kristallstruktur von Tetraphenylarsonium-hydrogendichlorid As(C6H5)4 [C12H] A New Synthesis, the Vibrational Spectrum and the Crystal Structure of Tetraphenylarsonium Hydrogendichloride AsfCeHsMC^H]  
 Abstract    As(C6H 5)4 + [Cl2H]-crystallizes in the monoclinic space group B2/b with four formula units per unit cell, the lattice constants being a— 1704, 6= 1751, c — 705 pm and y = 92.73°. The crystal structure was determined and refined from X-ray diffraction data to a residual index of R = 0.043. The CI2H-ion is situated on an inversion center with a C1---C1 distance of 309 pm. The IR and Raman spectra confirm the presence of sym-metrical CI2H -ions; the observed splitting of IR bands can be explained by factor group analysis. A simple procedure for the preparation consists of the reaction of HCl with As(C6H 5)4Cl.

 Title    Polymere Dimethyl-und Diphenylglyoximatokomplexe des Cobalts und Eisens mit 4.4' -Bipyridin als Brückenligand. Die Kristallstruktur des Bis(dimethylglyoximato)4.4'-bipyridincobalt(II)* Polymeric Dimethyl-and Diphenylglyoximato Complexes of Cobalt and Iron with 4,4'-Bipyridine as a Bridging Ligand. The Crystal Structure of Bis(dimethylglyoximato)4,4'-bipyridine Cobalt(II)  
 Abstract    Polymeric bis(dimethyl-and diphenylglyoximato)-complexes of Fe(II) and Co(II) with 4,4'-bipyridine as a bridging ligand have been synthesized from the glyoximato metal complexes and 4,4'-bipyridine in ethanol. The Co(II) compounds are paramagnetic and surprisingly stable against oxidation. The iron complexes are weak electrical conductors with approximately 10 -9 ß -1 cm _1 . Bis(dimethylglyoximato)-4,4'-bipyridine cobalt(II) crystallizes triclinic in the space group PT with Z — 1. The crystal structure is built up by linear chains of alternating Co(II) glyoximato complexes and axial bonded 4,4'-bipyridine bridges. The compound is characterized by strong Co-N-bonds of 189 pm within the glyoximato moiety and weak bonds of 228 pm to the bipyridine ligand. The two hetero-cycles of the bipyridine are coplanar, therefore the local symmetry of the complex is D 2

 Title    Gemischtvalente Bromoaurate(I,III) und ihre Mößbauer-Spektren Mixed Valent Bromo Aurates(I.III) and their Mößbauer Spectra  
 Abstract    New nonstoichiometric cesium bromo aurates(I,III) Csi+a;(AuBr4)(AuBr2, Br3,Br)z have been synthesized, in which the almost equally shaped anions AuBro -and Br3~ can inter-change themselves. The compounds crystallize in a disordered cubic perovskite structure with a = 547.5 pm or in a tetragonal superstructure with a 16-fold perovskite cell (a = 1553, c = 1099 pm). The investigations show that other bromoaurates as the previously reported "Cs2AgAuBr6" can contain perceptible amounts of Br3 _ ions also. The IR and 197 Au Mössbauer spectra of the new bromoaurates and of Cs2AuoBr6 are discussed.

 Title    G. Schmid-R. Greese * Tetraschwefeltetraimid als Ligand in Übergangsmetallkomplexen 644 Tetrasulfur Tetraimide as Ligand in Transition Metal Complexes  
 Abstract    Tetrasulfur tetraimide reacts with (THF)M(CO)s (M = Cr, W) to form isolable complexes of the type (S4N4H4)M(CO)5 (1) and (S4N4H4)[M(CO)5]2 (2) respectively, m NMR and X-ray investigations show the metal to be coordinated to sulfur atoms. In solution partially dissociation of M(CO)s moieties is observed leading to different equilibria. They are studied by !H NMR.

 Title    Über Oxostannate(II), IV [1] Zur Kenntnis von Rb2Sn02 und K2Sn02 [2]  
 Abstract    The new compound RboSnOo was obtained as a light yellow powder by heating mixtures of the binary oxides (RbOo.48 + SnO, Rb: Sn = 2:1) under argon (sealed Ag cylinders, 600 °C, 3d). Subsequent annealing (550 °C, 8d and 500 °C, 17 d) led to light yellow transparent single crystals. Rb2Sn02 is extremely sensitive to moisture and decomposes into black products. It crystallizes orthorhombicly in the space group P2i2i2i~D|, with a = 5.76i, b = 7.493, 0= I I.I67 A, Z = 4, drö = 4.43 and dpyk = 4.46 gem-3 , R= 11.8 and i?w = 12.0%. Effective Coordination Numbers, ECoN, these via Mean Fictive Ionic Radii, MEFIR, and the Madelung Part of Lattice Energy, MAPLE, have been calculated. Isotypic K2Sn02 was obtained similarly as a brown powder, a = 5.57g, b = 7.246, c = 16.744 A.
