Electrochemical and spectroscopic studies on RuCl(PPh3)2(N)2 and RuCl2(PPh3)2((N-N)

Abstract

A series of RuCl2(PPh3)2(N)2 and RuCl2(PPh3)2(N–N) complexes were synthesized from RuCl2(PPh3)3, (N)2=pyridine (py), 4-(N,N-dimethylamino)pyridine (4-dmNpy), 4-tert-butylpyridine (4-tBu-py), 4-methylpyridine (4-Mepy), 4-vinylpyridine (4-Vpy), 4-phenylpyridine (4-Phpy), isonicotinamide (4-CONH2py), 4-cyanopyridine (4-CNpy) N–N=1,10-phenanthroline (phen), 2,2′-bipyridine (bipy), 2,2′-bipyridine-4,4′-dimethoxy (MeO-bipy), 2,2′-bipyridine-4,4′-dimethyl (Me-bipy), 2,2′-bipyridine-4,4′-dithiomethyl (MeS-bipy), 2,2′-bipyridine-4,4′-dichloro (Cl-bipy) and 2,2′-bipyridine-4,4′-dinitro (NO2-bipy). The complexes were characterized by elemental analysis, cyclic voltammetry and UV–Vis, NMR and IR spectroscopies. The structure of the RuCl2(PPh3)2(phen) was established by single crystal X-ray crystallography.
