The Thermolysis of [Ru3(CO)12] in Cyclohexene: Synthesis and Charaterisation of the New Clusters [Ru3H2(CO)93121-C6H8)] and [Ru5(CO)1242-C6H8)(η4-C6H8)]

Thermolysis of [Ru3(CO)12] in cyclohexene for 24 h affords the complexes [Ru(CO)34-C6H8)] (1), [Ru3H2(CO)92121-C6H8)] (2), [Ru4(CO)124-C6H8)] (3) [Ru4(CO)94-C6H8)(η6-C6H6)] (4a and 4b, two isomers) and [Ru5(CO)1242-C6H8)(η4-C6H8)] (5), where 1, 3, 4a and 4b have been previously characterised as products of the thermolysis of [Ru3(CO)12] with cyclohexa-1,3-diene. The molecular structures of the new clusters 2 and 5 were determined by single-crystal X-ray crystallography, showing that two conformational polymorphs of 5 exist in the solid state, differing in the orientation of the cyclohexa-1,3-diene ligand on a ruthenium vertex.
