High-nuclearity mixed-metal carbonyl clusters of osmium and palladium; molecular structures of [Os5Pd6(CO)13(m-CO)5(m-H)2(m-dppm)2].2CH2Cl2.C6H14 and [Os5Pd6(CO)13(m-CO)6(m-dppm)2

The high-nuclearity mixed-metal carbonyl clusters [Os5- Pd6(CO)13(µ-CO)5(µ-H)2(µ-dppm)2] 1 and [Os5Pd6(CO)13- (µ-CO)6(µ-dppm)2] 2 are synthesized from the reaction of [Os3(CO)10(µ-H)2] with [Pd2(µ-dppm)2Cl2]; their molecular structures are determined by X-ray analysis
