The question of ‘open’ or ‘closed’ bimetallic phosphinidene (and heavier congeneric) complexes
Abstract
The reaction of ArPCl2(Ar = 2,4,6-But3C6H2) with Na[Co2(µ2-CO)2(η-C5H5)2] affords the ‘open’ phosphinidene complex, Co2(µ2-PAr)(η-C5H5)2(CO)2, the structure of which has been determined by X-ray crystallography.
