The reaction of [Cp2MH2] (Cp=C5H5; M=Mo, W) with AgX (X = BF4, PF6) in a 2:1 molar ratio yields [Ag(Cp2MH2)(2)]X (1). X-ray crystal structure analyses show nearly linear coordination at the silver ion. The silver halide complexes with [Cp2MoH2] exhibit a diversity of structures. For instance, in [Ag(Cp2MoH2)(2)Cl] (2) the coordination of the silver ion by two [Cp2MoH2] ligands and the chloride ion is trigonal planar. The hydride ligands are located by using the difference Fourier method, The clusters [Ag-3(Cp2MoH2)(3)X-3] (X = Br, I) (3) are formed in the reaction of [Ag(Cp2MoH2)(2)]BF4 with [N(nBu)(4)]X. X-ray crystal structure analyses reveal that these trinuclear clusters contain two different halide bridges and a single short Ag-Ag distance. The complex [Ag-3(Cp2MoH2)(4)Br-2]PF6 (4) with two different bromide bridges has an unusual trinuclear structure in which two silver ions are each bound to one [Cp2MoH2] ligand, and one silver ion is bound to two [Cp2MoH2] ligands.
