Molecular and Crystal Structures of Pentafluorophenyl-platinum(II) Complexes with Bis(diphenylphosphino)methane, Bis(diphenylarsino)methane and 1,2-Bis(diphenylarsino)ethane

The X-ray crystal structures of [PtCl2(dppm)], [Pt(C6F5)(2)L] (L = dppm (bis(diphenylphosphino)methane), dpam (bis(diphenylarsino)methane), dpae (bis(diphenylarsino)ethane)) and [PtCl(C6F5)(dpae)] show the complexes to be monomeric with chelating dipnictido ligands, and not alternatives with bridging ligands. In [Pt(C6F5)(2)(dpam)(2)], there are two unidentate diarsine ligands in a cis-arrangement.
