Synthesis, characterisation, molecular and crystal structures of two novel osmium–palladium carbide carbonyl clusters
Abstract
The pentaosmium carbide cluster [Os5C(CO)15] reacted with [Pd(PPh3)4] in CH2Cl2, giving a new hexanuclear osmium–palladium carbide cluster [Os5PdC(CO)12(µ-CO)2(PPh3)2] in moderate yield; treatment of [Os5C(CO)15] with [PdCl2(PPh3)2] in refluxing chloroform gave [Os5PdC(CO)15(µ-Cl)2(PPh3)] in low yield, which consists of a novel metal core geometry with a Pd–C (carbide) bond.
