Abstract

Thermolysis of [Ru-3(CO)(12)] in cyclohexene for 24 h affords the complexes [Ru(CO)(3)(eta(4)-C6H8)] (1), [Ru3H2(CO)(9)(mu(2)-eta(1):eta(2):eta(1)-C6H8)] (2), [Ru-4(CO)(12)(mu(4)-C6H8)] (3) [Ru-4(CO)(9)(mu(4)-C6H8)(eta(6)-C6H6)] (4a and 4b, two isomers) and [Ru-5(CO)(12)(mu(4)-eta(2)-C6H8)(eta(4)-C6H8)] (5), where 1, 3, 4a and 4b have been previously characterised as products of the thermolysis of [Ru-3(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.
