Functionalized Cobalt Clusters. Properties of Carboxylate Clusters CO)6Co2HCCCOOH and (CO)10cO4hcccooh as related to their structures

Abstract

Reaction of propiolic acid (HCCCOOH) with dicobalt octacarbonyl (Co2(CO)8) and tetracobalt dodecacarbonyl (Co4(CO)12) leads to the organometallic carboxylic acids (CO)6Co2HCCCOOH (1) and (CO)10Co4HCCCOOH (2) in good yield. Both organometallic compounds
