Abstract

The ionic coupling of [Os4H2(CO)12]2- with [Ru(η6-C6H6)(MeCN)3]2- affords the neutral mixed metal cluster Os4Ru( μ-H)2(CO)126-C6H6) 1. The reaction of 1 with trimethylphosphite leads to the initial formation of the addition product Os4Ru( μ-H)2(CO)126-C6H6)P(OMe)3 2, but this complex rearranges in solution to give Os4Ru( μ-H)3(CO)1236-C6H5)P(OMe)3 3. An X-ray structure of 3 shows that the metal core of the cluster is a ruthenium-spiked Os4 tetrahedron, with one hydrogen atom from the arene having transferred to the Os4 core, and one arene carbon bridging an Os-Os edge, while the ring as a whole remains η6-bound to the Ru atom.
