A novel tantalum butterfly oxo cluster
Abstract
(η5-C5Me5)Ta(H)2(η2-CHPMe2)(PMe3) reacts with deoxygenated water in benzene to give the novel tetranuclear butterfly oxo cluster [(η5-C5Me5)Ta]4(µ2-O)4(µ3-O)2(µ4-O)(OH)2 containing doubly, triply, and quadruply bridging oxo ligands, the X-ray crystal structure of which has been determined.
