Four ruthenium (II) complexes of the formulae [Ru(bpy)(L1) 2](ClO4)2 ? H2O (A1), [Ru(bpy)(L2)2](ClO4)2 ? H 2O (A2), [Ru(bpy)(L3)2](ClO4) 2 ? H2O (A3), [Ru(bpy)(L4) 2](ClO4)2 ? H2O (A4) (where L1 = N-(2-pyridylmethylene) phenyl amine, L2 = N-(2-pyridylmethylene) 4-(methyl) phenyl amine, L3 = N-(2-pyridylmethylene) 4-(chloro) phenyl amine, L4 = N-(2-pyridylmethylene) 4-(fluoro) phenyl amine and bpy = 2,2′-bipyridyl) have been synthesized. In addition to these ruthenium complexes, we have also been able to isolate four imidazopyridinium perchlorate compounds B1-B4 from the same reactions. The X-ray crystal structures of one representative ruthenium complex (A2) and the imidazopyridinium perchlorate compound (B2) have been determined. The Ru(II) center in the complex is coordinated by six N donors with a distorted octahedral geometry. The imine ligands (L) act as bidentate N,N donors.
