 Title    Synthese und Struktur des Trifluoracetyldicyanomethanids Synthesis and Structure of Trifluoroacetyldicyanom ethanide  
 Abstract    A suspension of NaCN in CH3CN was treated with excess of C2F4. The resulting red solution was evaporated to dryness and a red amorphous solid remained. One part of this solid was dissolved in water and a solution of Ph4AsCl was added. During the work-up procedure two salts were isolated, yellow [Ph4A s'][C F 3C (0)C (C N)2~] l a and red [Ph4A s+][(NC)2CC(CN)C(F)NC(CN)2_] 2a. The products were characterized on the basis of field desorption mass spectroscopy for positive and negative ions, l a was further characterized by an X-ray single crystal investigation.

The species Cp(CO) 2 Mo(w-S(CH 2)")Mo(CO) 2 Cp were isolated and charac-terized by their analytical and spectroscopic data. X-Ray structure analysis of the compound Cp(CO) 2 Mo(w-S(CH 2) 6)Mo(CO) 2 Cp proved the cyclic sulfide to act as a bridging ligand.

 Title    The Ni(0)—C0 2 System: Structure and Reactions of [Ni(PCy 3 ) 2 (i/ 2 -C0 2 )]  
 Abstract    The reactions of a variety of bis(tricyclohexylphosphine)nickel species with C0 2 have been studied. The product of the reaction is solvent dependent: in toluene the known complex [NiL 2 (/7 : -C0 2)]-toluene (L = PCy 3) is formed while in ether or pentane a binuclear complex [(NiL 2) 2 (?;-C0 2)] results through the intermediacy of the solvent free species [NiL 2 (// 2 -C0 2)] the structure of which has been determined by X-ray crystallography.

 Abstract    The phase-transfer-catalytically in situ generated dihalocarbenes CC1 2 and CBr 2 are inserted into a ß-C—H bond of the five-and six-membered phosphamanganacycloalkanes (OC) 4 MnPPh 2 (CH 2)"CH 2 CH 2 (la, b) [n = 1(a), 2(b)] to give the functionalized metallacycles (OC) 4 MnPPh 2 (CH 2)"CH(CHX 2)CH 2 (2a, a', b, b') [X = Cl: n = l(a), 2(b); X = Br: n = l(a'), 2(b')]. 2b crystallizes in the orthorhombic space group Pbca with Z = 8 and has a distorted chair conformation with equatorial position of the CHC1 2 group. The envelope conformation of 2a in solution was elucidated by means of 'H and 13 C{'H} NMR spectroscopic investigations.

 Title    Kaliumlithiumsulfid, KLiS: Das erste Interalkalimetallsulfid Potassium Lithium Sulphide, KLiS: The First Inter Alkaline Metal Sulphide  
 Abstract    The compound KLiS has been prepared and its crystal structure is determined by X-ray dif-fraction techniques. The hygroscopic, yellow compound crystallizes in the tetragonal space group P4/nmm (Z = 2) with the cell parameters a — 431.79(4), c = 696.20(9) pm. The structure was solved from 2100 counter reflections (356 symmetry independent reflections) through a Patterson synthesis and refinement by Fourier syntheses to a least squares residue of 0.026. The structure is characterized by c-centered squares of lithium layers interspersed by anti-parallel ordered K—S-pairs forming an anti-PbFCl-type geometry.

 Title    Preparation and Crystal Structure of a New Mixed Valence Cerium Germanate Ce2 + Ce! + [Ge0 4 ]3[Ge20 7 ]2[Ge 3 0 1 o]  
 Abstract    Opaque blue crystals of a new mixed valence cerium germanate have been prepared at elevated temperatures (1555 K) under careful thermoanalytical control. Single crystal structure analysis shows three different types of germanate anions [Ge0 4 ] 4 ~, [Ge 2 0 7 ] 6 ~ and [Ge 3 O 10 ] 8 ~, all ger-manium atoms being in tetrahedral coordination. Due to the larger number of oxygens per unit cell (Ce 2 Ge 2 0 72), with all the oxygens unambiguously located by X-ray single crystal structure analysis, this phase differs significantly from the corresponding cerium(III) germanate Ce 2 Ge 2 0 7 , which shows [Ge0 4 ] 4_ and [Ge 3 Oi 0 ] 8 ~, but no [Ge 2 0 7 ] 6 ~ ditetrahedral groupings.

 Title    Dynamics and Structure of Phosphite Substituted Olefintungsten Complexes  
 Abstract    The barriers of rotation of olefin ligands in (OC) 3 LL'W(olefin) complexes, L — P(OMe) 3 , L' = P(OMe) 3 or P(OEt) 3 , olefin = ethylene, methylmaleate, methylfumarate, methylacrylate (1—4) have been determined from D-NMR measurements. The preferred olefin orientation has been deduced from an X-ray analysis of the tricarbonyl-triethylphosphite-trimethylphosphite-methyl-maleatetungsten compound 2. The influence of steric and electronic factors on the rotational process has been discussed by use of EHT-calculations.
