Abstract
Trinuclear clusters M3(CO)12(M=Ru and Os) react with 2,3-dihydroxyquinoxaline (DQ) to give M(CO)2 (DQ) (DMSO) products. I.r. and n.m.r. spectroscopy show these complexes are trigonal bipyramidal with the two CO molecules differently bonded to the metal center; axially in the ruthenium complex and equatorially in the osmium complex. Prolonged heating of ruthenium(III) chloride with DQ gave the [Ru(DQ) (DMSO)3]Cl3 complex, the i.r. spectrum of which showed that the ligand is bonded to the metal in the catecholate form.
