摘要：

The two new platinum-osmium carbonyl cluster complexes Pt2Os4(CO)12(COD)2 (1) and Pt2Os4(CO)11(COD)2 (2) were obtained from the reaction of Pt2Os4(CO)18 with 1,5-cyclooctadiene (COD) at 97-degrees-C. Both compounds consist of a bicapped Os4 tetrahedron. Compound 1 is coordinatively saturated, while compound 2 is coordinatively unsaturated. The latter contains several unusually short metal-metal bonds and readily adds CO to give 1 in good yield.
