Abstract

Treatment of [Os4H4(CO)11]2-, [Os10C(CO)24]2- and [Ru10C(CO)24]2- with [Au2(Ph2PCH2PPh2)Cl2] in the presence of an excess of TIPF6, gave [Os4H4(CO)11(Au2Ph 2PCH2PPh2)] 1, [Os10C(CO)24(Au2Ph2PCH 2PPh2)] 2 and [Ru10C(CO)24(Au2Ph2PCH 2PPh2)] 3, respectively, all of which were obtained in high yield. The structures of the clusters l and 3 have been established by X-ray crystallography, both exhibiting novel coordination modes of the bidentate gold fragments. Cluster 1 contains a tetrahedral Os4 core with one of the Au atoms of the Au2(Ph2PCH2PPh2) ligand bridging an edge of the tetrahedron, and the second Au atom coordinated to a third Os atom. In 3 the two Au atoms of the Au2(Ph2PCH2PPh2) ligand cap two adjacent, vertex sharing, triangular faces of the Ru10 tetracapped octahedral core.
