Abstract

The complexation reaction of trans-[RuCl2(Dpte)2] (Dpte – (diphenylthio)ethane) with mixed diimine ligands 2,2"-bipyridine, pyridylquinoline, 4,6-dichloro-2-(2-pyridyl)pyrimidine, 4,6-dichloro-5-methyl-2-(2-pyridyl)pyrimidine, and 4,6-dichloro-5-phenyl-2-(2-pyridyl)pyrimidine produces new Ru(II) mixed-ligand complexes. These complexes exhibit maximum photo- and chemical stability and high absorptivity. The above complexes have been characterized using IR, 1H and 13C NMR, electronic absorption spectroscopy, and elemental analysis.
