A complete series of homo- and heterobimetallic complexes of the type [MM′(dppm)2(CH3CN)2] (BF4)2 (M, M′ = Ni, Pd, Pt; dppm = Ph2PCH2PPh2) have been prepared by comproportionation of appropriate M(0) and M′(II) complexes. These complexes have been characterized by 1H and 31P NMR spectroscopy. NMR evidence shows that the acetonitrile ligands are labile for all complexes containing nickel and palladium. For certain heterobimetallic complexes, a second isomer is observed involving one bridging and one chelating dppm ligand while preserving the metal-metal bond.
