Abstract

Reactions between [M2(dppm)2(NCMe)2]X2 [M = Ag, X = ClO4; M = Cu, X = BF4] and Ru(C≡CC≡CM)(dppe)Cp∗ [M = Ag, Cu; generated in situ from Ru(C≡CC≡CH)(dppe)Cp∗ and AgNO3 or CuCl(PPh3), respectively] afford the cationic mixed-metal cluster diynyl complexes [M6{μ3-C≡CC≡C[Ru(dppe)Cp∗]}4(μ-dppm)2]X2, of which the structures were determined by single-crystal XRD studies. Electrochemical studies indicate that there is no interaction between the ruthenium centres. Reactions between [M2(μ-dppm)2(NCMe)2](BF4)2 and Ru(C≡CC≡CM′)(dppe)Cp∗ (M,M′ = Cu, Ag) afforded a mixture of Ag6−nCun clusters, as shown by ES-MS and crystallographic studies. Preliminary studies suggest that extensive disproportionation occurs in solution.
