The unsaturated clusters Os4(CO)12(AuPR3)2 [PR3 = PEt3 (I), PPh3 (II), PMePh2 (III)] may be prepared by the thermal decarbonylation of Os4(CO)13-(AuPR3)2 [PR3 = PEt3 (IV), PPh3 (V), PMePh2 (VI)] which have been obtained previously by the reaction of [Os4H-(CO)13]- with 2 equiv of Au(PR3)Cl. The former reaction is reversible, and clusters I, II, and III readily add a range of nucleophiles as well as undergoing facile sequential, electrochemical reductions, to [Os4(CO)12-(AuPR3)2]- and [Os4(CO)12(AuPR3)2]2-. The existence of the monoanionic species is confirmed by the observation of an ESR spectrum, while X-ray crystallographic studies on III and IV show open bicapped butterfly and diedge-bridged tetrahedral metal frameworks, respectively.
