A series of RUCl2(PPh3)(2)(N)(2) and RUCl2(pPh(3))(2)(N - N) complexes were synthesized from RuCl2(PPh3)(3), (N)(2) = pyridine (py), 4-(N,N-dirnethylamino)pyridine (4-dmNpy), 4-tert-butylpyridine (4-' Bu-py), 4-methylpyridine (4-Mepy), 4-vinylpyridine (4-Vpy), 4-phenylpyridine (4-Phpy), isonicotinamide (4-CONH(2)py). 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 U-V-Vis, NMR and IR spectroscopies. The structure of the RUCl2(PPh3)(2)(phen) was established by single crystal X-ray crystallography. (C) 2001 Elsevier Science Ltd. All rights reserved.
