Facile interconversion of terminal, doubly bridging, and quadruply bridging carbonyl ligands in solution: crystal structure and solution dynamics of the complexes LWRu3(CO)12H, L = C5H5 and C5Me5
Abstract
The crystal structures of the tetranuclear mixed-metal complexes LWRu3(CO)12H, L = C5H5 and C5Me5, were determined, indicating the presence of a butterfly arrangement with an unusual µ4-η2-CO ligand; in solution, these isomers are in equilibrium with other isomers containing only normal σ-bonded CO ligands.
