New A-frame cluster complexes have been prepared by addition of electrophilic gold fragments to the Pt-Pt bond of , dppm = Ph2PCH2PPh2.For example, gave and gave NO3.The complexes reacted with to give BF4 when n = 1 or 2, but the bridged bis(A-frame) cluster complex 2CH2>(BF4)2 when n = 3.In contrast, CuCl reacted with to give .Attempts to synthesize A-frame clusters containing Pt2Ag, Pt2Cu, Pd2Au, or PdPtAu units were unsuccessful, and it is concluded that these units are considerably weaker than the analogous 3-center 2-electron bond of the Pt2Au unit.The AuCl unit is displaced from on reaction with diazomethane, with formation of .Key words: platinum, gold, cluster, copper, silver.

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.
