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.
