Seven ruthenium(II) complexes continuing substituted diimine ligands and the azoimine ligand (Az: C6H5N{double bond, long}NC(COCH3){double bond, long}NC6H5) are synthesized and characterized. trans-[Ru(II)(Az)(L)Cl2] [L = 2,2′-bipyridine (bpy) 1, 4,4′-dimethyl-2,2′-bipyridine (dmb) 2, 4,4′-dimethoxy-2,2′-bipyridine (dmeb) 3, 4,4′-di-tertbutyl-2,2′-bipyridine (dtb) 4, 1,10-phenanthroline (phen) 5, 5-amino-1,10-phenanthroline (NH2phen) 6, 5-chlorophenanthroline (Clphen) 7, 3,4,7,8-tetramethyl-1,10-phenanthroline (tmphen) 8] are made by the reaction of RuCl3 hydrate and the ligands in the presence of LiCl. These complexes have been characterized by cyclic voltammetry, UV-Vis spectroscopy, electrochemical measurements and X-ray diffraction analysis for 2 and 5. The electrochemical parameters (EL(L)) of the substituted diimine ligands (L) are reported. The absorption spectrum of 5 in acetonitrile has been modeled by time-dependent density functional theory (TD-DFT) using a hybrid functional, B3LYP, as well as the LanL2DZ basis set.
