 Title    Darstellung und Charakterisierung von "Nitrenkomplexen"  
 Abstract    des Molybdän und Wolfram der Zusammensetzung [(^-C5H5)OM]2(/*-NCOOC2H5)2 (M = Mo, W) und [(^-C5H5)0Mo]2(^-NC02C2H5)(^-0) Synthesis and Characterization of "Nitrene Complexes" of Molybdenum and Tungsten of Composition [(^-C5H5)0M]2(/<-NC02C2H5)2 (M = MO, W) and [(^-C5H5)0Mo]2(^-NC00C2H5)Gu-0) The photolytical reactions of 7? 5 -C5H5Mo(CO)3CH3 (1) or 7? 5 -C5H5W(CO)3CH3 (2) with N3C02C2H5 (3) in CH2C12 yield the "nitrene" complexes [(^-CsHsJMoOJ^-NCC^Hsfe (4), [(r? 5 -C5H5)W0]2(/u-NC02C2H5)2 (5) and [(^-CsHsJMoOM^-NCO^HsM^-O) (6) together with some *? 5 -C5H5Mo(CO)3Cl (7) and ^ 5 -C5H5W(CO)3Cl (8), proving that the solvent takes part in the reaction. Compounds 4, 5 and 6 contain bridging imido groups, arising from the capture of probably free nitrenes NC02C2Hs by organometallic species. Evidence for the presence of free nitrenes in the reaction medium is provided by the isolation of urethane (9), tetrachlorethene (10), 7 and 8 as secondary products.

 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    Synthese und Kristallstruktur eines Triazido-nitrido-bipyridyl-Komplexes des Molybdäns(VI): MoN(N3)3(bipy) Synthesis and Crystal Structure of a Triazido Nitrido Bipyridyle Complex of Molybdenum(VI): MoN(N3)3(bipy)  
 Abstract    The reaction of MoCl^bipy) with an excess of (CH3)3SiN3 in 1,2-dichloroethane results in the formation of a mixture of MoN(N3)3(bipy) and Mo(N2)Cl2(bipy). The latter is an insoluble, brownish compound of yet unknown structure. MoN(N3)3(bipy) is very soluble in 1,2-dichloroethane and easily hydrolysed. It can be crystallized from toluene in the form of explosive, red crystals of the space group P 2i\n. The crystal structure is built up by monomeric complexes, in which the Mo atom has a distorted sixfold coordination. The three azido groups are located eis to the nitrido ligand, with their free electron pair at the a-N-atom pointing away from the closely neighbouring nitrido ligand. The bipyridine forms two bonds of quite different length (224,0 and 241,9 pm) with the Mo atom, as trans to the triply bounded nitrido ligand (Mo = N = 164,2 pm) only a weak interaction is possible.

Die Kristallstruktur des Bis(dimethylglyoximato)pyrazin-cobalt(II) + Polymeric Dimethyl-and Diphenylglyoximato Complexes of Cobalt and Iron with Pyrazine as a Bridging Ligand. The Crystal Structure of Bis(dimethylglyoximato)pyrazine Cobalt(II)+  
 Abstract    Polymeric bis(dimethyl-and diphenylglyoximato)-complexes of Fe(II) and Co(II) with pyrazine as a bridging ligand have been synthesized. The Co(II) complexes are para-magnetic with n = 1.83 B.M., and surprisingly stable against oxidation. Bis (dimethyl-glyoximato)pyrazine-cobalt (II) crystallizes monoclinic in the space group C2/m with Z = 2. The crystal structure shows linear chains of alternating Co atoms and pyrazine ligands. Perpendicular to the chain, the Co atoms are coordinated in a square planar arrangement by two dimethylglyoximato ligands (Co-N= 189 pm), the local symmetry being C2h-The long Co-pyrazine distance of 224 pm is in agreement with the fact that the compound is a 19 electron complex. The Co complexes do not have conducting properties. The Fe(II) complexes possess the same structure but with stronger bonds in the chain. They show very low conductivity of approximately 10 -10 cm -1 Q~ l . The Mössbauer spectra of the Fe-complexes are reported.

 Title    Nitrido-azido-Komplexe des Molybdäns(VI) Synthese und Kristallstruktur von MoN(N3)3(NC5H5) Nitrido Azido Complexes of Molybdenum (VI) Synthesis and Crystal Structure of MoN(N3)3(NC5H5)  
 Abstract    The explosive nitrido azido complexes MoN(N3)Cl2 • py and MoN(N3)3py are prepared by the reaction of MoCLi(py)2 with (CH3)3SiN3 in 1,2-dichloroethane. Both compounds hydrolyze quickly in moist air. After separation of the insoluble, black MoN(N3)Cl2 • py from the solution of MoN(N3)3py, the latter can be obtained in form of monoclinic, red crystals of the space group C2/c. Its structure consists of monomeric complexes, wherein the Mo atom has a square pyramidal coordination. The nitrido ligand occupies the apex and forms a strong multiple bond of 163.4 pm to the Mo atom. cr-Bonds of different strength exist between the Mo atom and the basal ligands: M0-N3 — 204.3 pm; Mo-py = 225.8 pm. The a-N atoms of the azido groups are sp 2 hybridized, with their lone pair pointing away from the nitrido ligand. The pyridine ligand forms an angle of 61.6° to the basal plane of the coordination polyhedron.

 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.

Diiodocuprate(I) RCuI2 mit isoherten Ketten ^ [Cul4 2~] * R 1 = N-Methylpyridinium, R 2 = Dimethyl ( 3 -dimethylamino -2 -aza -2 -propenyliden ) ammonium [1] Syntheses and Structure Analyses of Iodocuprates(I): II. Diiodocuprates(I) RCUL2 with Isolated Chains [CULI/2~]; R 1 = N-Methylpyridinium, R 2 = Dimethyl(3-dimethylamino-2-aza-2-propenyliden) Ammonium  
 Abstract    N-Methylpyridinium-diiodocuprate(I), CßHgNCuI^ and dimethyl(3-dimethylamino-2-aza-2-propenyliden)ammonium-diiodocuprate(I), C6H14N3CUI2, are obtained by reacting Cu with C6H8NI3 or C6H14N3I3 in acetone. Both compounds are built up by the organic cations and chains of edge sharing tetrahedra<jo[Cul4/2-]. The iodocuprate(I) anions are in intimate contact with the cations via intermolecular I • • • C interactions. Though nearly the same average Cu-I distance of 267.2 or 268.2 pm was found for both iodocuprate(I) anions there are different Cu-Cu distances (301-354 pm).
