‘Capped’ tri-ruthenium carbonyl cluster: X-ray crystal structure of [Ru3(CO)9{MeSi(PBu2)3}]
Abstract
The tridentate tertiary-phosphine ligand MeSi(PBu2)3 reacts with Ru3(CO)12 in refluxing benzene to give the symmetrical complex [Ru3(CO)9{MeSi(PBu2)3}], containing three bridging carbonyl ligands and one phosphorus centre co-ordinated to each of the ruthenium atoms as shown by X-ray crystallography.
