TIN, PALLADIUM AND PLATINUM DERIVATIVES OF 1,1'-BIS(DIPHENYLPHOSPHINE)FERROCENE - CRYSTAL AND MOLECULAR-STRUCTURES OF 1,1'-BIS(DIPHENYLPHOSPHINE)FERROCENEDICHLOROPALLADIUM(II) AND OF 1,1'-BIS(DIPHENYLPHOSPHINE)FERROCENEDICHLOROPLATINUM(II)

Ten derivatives of 1,1'-bis(diphenylphosphine)ferrocene (BDPF) are described in this paper. The first three, [BDPF.SnCl4] (1), [BDPF.MeSnCl(3)] (2) and [BDPF. PhSnCl(3)] (3), present the two phosphorus atoms of the ligand directly bonded to a Sn centre. Two others, [BDPF.PdCl2] (4) and [BDPF.PtCl2] (5), similarly have the ligand BDPF acting as a bidentate species towards a transition metal. The crystal and molecular structures of (4) and (5) are presented here. Two other BDPF complexes were obtained with Pd and Pt, with the transition metals in the zerovalent state, namely [Pd(BDPF)(2)] (6) and [Pt(BDPF)2] (7). Finally, three trimetallic complexes are also described; [BDPF.Pd(mu-Cl)(2)SnCl2] (8), [BDPF.Pt(mu-Cl)(2)SnCl2] (9) and [BDPF.PdClSnCl3] (10).
