Abstract : Binuclear complexes of Rh and Ir containing a flexibly bridging bis(acac) ligand have been synthesized and characterized. The reaction of M(micro-Cl)-(1,5-COD)2 (M=Rh,Ir) with p-xylylenebis(3-(2,4-pentanedione)), xyl(Hacac)2, + 2 equiv KOH results in the formation of the binuclear compounds (M(COD))2-xyl(acac)2. The cyclooctadiene ligand in these complexes is readily displaced from the metal centers by either CO or PPH3 leading to the formation of (M(CO)2)2xyl(acac)2 and (M(PPH3)2)2xyl(acac)2, respectively. The (M(CO)2)-xyl(acac)2 complexes react with excess triphenylphosphine, leading to the displacement of one CO from each metal center and the formation of (M(CO)(PPH3)2xyl(acac)2.
