[Cp2MoH2]-silver complexes with pseudohalide ligands

The reaction of [Cp2MoH2] and AgBF4 with the pseudohalide ligands SCN-, OCN -, CN- and SCF3- afforded the complexes [(CP2MoH2)(2)AgSCN] (1), [(Cp2MoH2) (2)AgNCO]. CH2Cl2 (2), [(Cp2MoH2)(2)Ag(C3N3H2O3)]. 3CH(2)Cl(2) (3), [(CP2Mo H2)(2)Ag](n)-[(Ag-2(CN)(3))(n)] (4) and [(Cp2MoH2)(2)AgSCF3]. CH2Cl2 (5). 1 , 2 and 5 have a [Cp2MoH2]:Ag:ligand stoichiometry of 2:1:1. Complex 3 cont ains the anion of the ligand (HNCO)(3), formed by trimerization of HNCO. Th e three-dimensional structure of 4 is built up of polymeric [Ag-2(CN)(3)(-) ](n) strings and [(Cp2MoH2)(2)Ag](+) units. The compounds 1-5 were characte rized analytically and spectroscopically. All the structures were determine d by single crystal X-ray analysis. (C) 2001 Elsevier Science BN. All right s reserved.
