Reactions between Ru3(μ-dppm)(CO)10 and cycloocta-1,3,5,7-tetraene (cot) in refluxing thf afford the four complexes Ru3(μ-dppm)(μ-C8H8XCO)6 (2), Ru3(μ3-PPhCH2PPh2)(μ3-C8H8)(Ph)(CO)5 (3), Ru3{μ3-PPhCH2PPh(C6H4)}(μ-C8H8)(μ-CO)(CO)4 (4) and Ru3(μ-H){μ3-PPh2CHPPh(C6H4)}(μ-C8H9)(μ-CO)(CO)4 (5) which have been structurally characterised by means of X-ray crystallography. Complex 3 is the first example of an Ru3 cluster containing a cot ligand capping the Ru3 face. In 2 and 4, the cot ligand is found bridging an Ru-Ru edge; in 2, only one Ru of this edge is bonded to a P atom. In 3, a P-C bond of the dppm ligand has oxidatively added to one Ru atom to give an unusual example of a cluster-bonded σ-phenyl group. Complex 5 contains a C8H9 ligand and dppm unusually dimetallated at the methylene carbon and at a phenyl group.
