The high yield synthesis of an unsaturated osmium cluster; the X-ray crystal structure of [Os3(CO)8(H){Ph2PCH2P(Ph)C6H4}]

Abstract

Thermolysis of [Os3(CO)10(dppm)](dppm = Ph2PCH2PPh2) in refluxing toluene affords a high yield of the unsaturated cluster [Os3(CO)8(H){Ph2PCH2P(Ph)C6H4}] which has been characterized by X-ray crystallography, and which undergoes a facile reversible reaction with CO.
