The chemistry of an 11-atom polyhedral metallocarborane prepared by polyhedral contraction
Abstract
The base degradation of [LCo(π-(3)-1,2-B9C2H11)]z followed by oxidation has been found to effect a polyhedral contraction to give [LCo(π-B8C2H10)]z where L =π-C5H5– and z= 0 or L =π-(3)-1,2-B9C2H112– and z=–1; these new compounds react with pyridine to afford the adducts [LCo(π-B8C2H10·C5H5N)]z which constitute the first reported examples of a nido-metallocarborane.
