 Title    Transition Metal Complexes with Sulfur Ligands, IV [1] Synthesis and Reactions of Mo (IV) Complexes with the Tetradentate Thioether-thiol Ligand 2,3,8,9-Dibenzo-l,4,7,10-tetrathiadecane  
 Abstract    Synthesis and characterization of non-oxo Mo(IV) complexes with the tetradentate thioether-thiol ligand 2,3,8,9-dibenzo-l,4,7,10-tetrathiadecane(dttd-H2) are reported. MoCl4(THF)2 reacts with dttd-H2 in THF at room temperature to give the paramagnetic (2.61 BM, 295 K) [Mo(dttd)Cl2]. The chlorine ligands in [Mo(dttd)Cl2] can be substituted by sulfur ligands yielding diamagnetic complexes as [Mo(dttd)(CeH4S2)], [Mo(dttd)(SC2HiS)] and [Mo(dttd)(SC2H5)2]; with Na2S, NaHS or H2S, the di-^-sulfido bridged complex [(dttd)Mo(S)2Mo(dttd)] is obtained. The reduction of [Mo(dttd)Cl2] by various reducing agents in the presence of CO or NO yields labile carbonyl and nitrosyl species in solution. In contrast to [Mo(dttd)Cl2], the complexes with MoSe cbromophores showed no reactivity to CO or NO under reducing conditions.

 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
