Metal–metal bond fission in a trinuclear osmium cluster by triethylphosphine: the X-ray crystal structure of [HOs3(CO)10(PEt3)(CF3CCHCF3)]
Abstract
The reaction of [HOs3(CO)10(CF3CCHCF3)] with PEt3 in hexane at room temperature leads to the formation of [HOs3(CO)10(PEt3)(CF3CCHCF3)] as the major product; a single crystal X-ray analysis reveals the presence of a chain of Os atoms, a terminal hydride ligand, and a vinylic group bridging two of the metal atoms.
