The reactivity of homobimetallic complexes of platinum(II) and palladium(II) containing diethyl(diphenylphosphinomethyl)amine (ddpa = (C6H5)2PCH2N(C2H5)2) as a bridging ligand has been investigated.Carbon monoxide reacts reversibly with these complexes.The species formed are binuclear carbonyl-bridged derivatives, which can isomerize to ionic terminal carbonyl complexes.Reaction of 2<(C2H5)4N>2 with ddpa in dichloromethane gives the ionic platinum(I) complex 2<(C2H5)4N>2, which reacts with carbon monoxide.Still, homobimetallic derivatives ofpalladium(I) are unstable, and none have been isolated.
