Synthesis and Characterization of Neutral Ru(III) Complexes Containing Schiff Bases and N-donor Heterocyclic Ligands

Abstract

Two new neutral complex compounds of Ru(III) with Schiff bases and N-donor heterocyclic ligands have been synthesized. Based on MALDI TOF/TOF mass spectra, CHN elemental analysis, infrared and electronic spectra the synthesized compounds were formulated as [RuCl(N-Ph-5-X-salim)₂B], where X = Cl for B = Py and X = Br for B = Pym. In the octahedral environment of Ru(III), bidentate Schiff bases acts as anionic ligand where coordination occurs via deprotonated phenolic oxygen and azomethine nitrogen atom. Coordination of monodentate N-donor heterocyclic ligands occurs through free electronic pair on the nitrogen atom.
