Abstract
The reactions between [M3(CO)12], M = Ru and Os, and salicylideneimine-2-thiophenol Schiff base in THF under reflux gave [Ru(CO) 4 (satpH)] and [Os(CO)3(satpH2)] complexes. Structures of the two complexes were proposed on the basis of spectroscopic studies. Magnetic study of [Ru(CO)4(satpH)] suggested that a change in oxidation state of the ruthenium atom from zero to +1 was achieved via oxidative addition of the SH group with a proton displacement to give a low-spin d7 electronic configuration. UV-Vis spectra of the two complexes in different solvents exhibited visible bands due to metal-to-ligand charge transfer. Electrochemical investigation of the free ligand and complexes showed some cathodic and anodic irreversible peaks due to interconversions through electron transfer. © 2004 Elsevier B.V.
