Thermolysis of a toluene solution containing [Fe2W(CO)103-S)2] (1) and [(η5-C5H5)Mo(CO)3(CCPh)] (2) in the presence of air at 70°C yields the mixed-metal cluster [(η5-C5H5)2Mo2WFe2(O)2(S)2(CO)9(CCPh)2] (3). The structure of 3 has been established crystallographically. It consists of a triangular Fe2W unit, each face of which is capped by a sulfido ligand. Each Fe atom bears three carbonyl groups, while the W atom is attached to two different Mo-containing moieties. It is π-bonded to the C≡C bond of a (η5-C5H5)Mo(CO)3(C≡CPh) unit, and it is also bonded to a second Mo atom, and this bond is bridged by an oxo group and a μ22-CCPh group. Also attached to this Mo atom is a terminal oxo group. Compound 3 has been investigated electrochemically.
