Reaction of the unsaturated mixed metal cluster [Os3(µ-H)(CO)10(µ-AuPR3)](R = Ph, Et) with carbon monoxide and the chemistry of the products; the X-ray crystal structure of [Os3(CO)10(µ-AuPEt3)2]
Abstract
The cluster [Os3(CO)10(AuPR3)2](RPh, Et) may be prepared by the decarbonylation of [Os3(CO)11(AuPR3)2], or by the direct reaction of [Os3H(CO)11]– or [Os3(CO)11]2– with two equivalents of Au(PR3)Cl; an X-ray analysis of [Os3(CO)10(AuPR3)2] shows that both ‘AuPR3’ groups bridge the same short edge of the Os3 triangle.
