摘要：
The trans-[RUCl2(L)(4)], trans-[Ru(NO)Cl (L)(4)](PF6)(2) (L = isonicotinamide and 4-acetylpyridine) and trans-[Ru(NO)(OH)(py)(4)]Cl-2 (py = pyridine) complexes have been prepared and characterized by elemental analysis, UV-visible, infrared, and H-1 NMR spectroscopies, and cyclic voltammetry. The MLCT band energies of trans-[RUCl2(L)(4) increase in the order 4-acpy < isn < py. The reduction potentials of trans-[RuCl2(L)(4)] and trans-[Ru(NO)Cl(L)(4)](2+) increase in the order py < isn < 4-acpy. The stretching band frequency. v(NO), of the nitrosyl complexes ranges from 1913 to 1852 cm(-1) indicating a nitrosonium character for the NO ligand. Due to the large pi-acceptor ability of the equatorial ligands, the coordinated water is much more acidic in the water soluble trans-[Ru(NO)(H2O)(py)(4)](3+) than in trans-[Ru(NO)(H2O)(NH3)(4)](3+) (C) 2009 Elsevier B.V.
