Thiolato-bridged tri- and dinuclear platinum complexes of the types [Pt-3(mu-SR)(4)(dppm)(2)](2+) (1) and [Pt-2(mu-ER)(2)(dppm)(2)](2+) (2) (E = S or Se; R = alkyl or aryl; dppm = bis(diphenylphosphino)methane) have been prepared using the mononuclear precursors [Pt(ER)(2)(dppm)]. The complexes have been characterized by NMR (H-1, C-13, P-31 , Pt-195), FT-IR and FAB mass spectral data. The structure of [Pt-3(eta-SC6H4CH3-4)(4)(dppm)(2)][CF3SO3](2).6CH(2)Cl(2) (1d), has been established through X-ray crystallography, revealing a zig-zag arrangement of the three coordination spheres around the platinum atoms.
