Electrochemical studies indicate that there is no interaction between the ruthenium centres. Reactions between [M<inf>2</inf>(μ-dppm)<inf>2</inf>(NCMe)<inf>2</inf>](BF<inf>4</inf>)<inf>2</inf> and Ru(C{triple bond, long}CC{triple bond, long}CM′)(dppe)Cp* (M,M′ = Cu, Ag) afforded a mixture of Ag<inf>6-n</inf>Cu<inf>n</inf> clusters, as shown by ES-MS and crystallographic studies. Preliminary studies suggest that extensive disproportionation occurs in solution. © 2010 Elsevier B.V. All rights reserved.en(c) 2010 Elsevier B.V.
