The title bimetallic compound, [PtCl(2){Co(C(17)H(14)P)(2)}]PF(6), was obtained by reaction of 1,1'-bis-(diphenyl-phosphino)cobalto-cenium hexa-fluorido-phosphate with bis-(acetonitrile)di-chloridoplatinum. The Pt(II) ion is four-coordinated in a slightly distorted square-planar environment by two P atoms of the 1,1'-bis-(diphenyl-phosphino)cobaltocenium moiety and two Cl atoms. In the crystal structure, mol-ecules are linked by weak C-H⋯F and C-H⋯Cl hydrogen bonds.
