Bis{(diphenylphosphinoethyl)phenylphosphino}methane (DPPEPM) reacts with [PtR2(cod)] in 1:1 ratio to give [PtR2 (DPPEPM-PP)] (2a, R = Me; 2b, R = Ph), whereas with [PtCl2(cod)] or [PdCl 2(cod)] it yields the ionic species [M(DPPEPM-PP)2] 2+ (3 and 4). With [MClMe(cod)], the product is [MMe(DPPEPM-PPP)]+ (5, M = Pt; 6, M = Pd), in which one of the internal P atoms of the ligand is uncoordinated. These complexes undergo oxidation of the free P atom to give 7 and 8 on standing in solution. Complexes 2-4 may be used to construct bimetallic and trimetallic mixed metal complexes. The molecular structures of 7 and [PtMe2(μ-DPPEPM)PdCl 2] (11) are reported.
