New mode of ‘benzyne’ co-ordination. Crystal and molecular structure of Os3(CO)9(PEt)(C6H4)
Abstract
The benzyne ligand in Os3(CO)9(PEt)(C6H4) is shown by X-ray crystallography to be asymmetrically bound with one carbon atom σ-bonded to one osmium while a second bridges the two other metal atoms; a low energy process interchanges these two sites in solution.
