3 X 2] 2 (X= Cl, Br) have been studied in different solvents and a tentative assignment of the
bands observed made. The change with time of the IR spectra in chloroform solution
observed by several authors is due to the interaction of the compounds with the ethanol
present in the solvent as stabilizer. The reactions of [Ru (CO) 3 X 2] 2 (X= Cl, Br) with
oxygenated solvents, nitrogen and phosphorous ligands are described. Some complexes of …
