Abstract
The first undeca-osmium cluster, [Os11 C(CO)27] 2- (1), has been isolated as a low-yield product of the vacuum pyrolysis of Os3(CO)12; the dianion (1) reacts with 1 equivalent of [Cu(NCMe)4][BF4] to give the monoanion [Os11C(CO)27Cu(NCMe)]- (2) which has been shown by X-ray analysis to have an unusual Os11 core geometry with the carbido atom occupying a trigonal prismatic cavity.
