Abstract: Five heteroleptic ruthenium(II) complexes of formulae[Ru(RPy)2(MeaaiMe)2](ClO4)2.H2O (1 -5) (MeaaiMe = p-MeC6H4-N=N-C3H2, RPy: R = H (Pyridine, 1), o-Me (o-methylpyridine, 2), p-Me (p-methylpyridine,3), p-NMe2 (p-N,N-dimethylpyridine, 4). p-Cl (p-chloropyridine, 5) have been synthesized from ctc-[RuCl2(MeaaiMe)2] + AgNO3 and RPy. The complexes are characterized by IR, UV -Vis and 1H-NMR spectral data. They exhibit high intense MLCT transition in 520-545 nm. Cyclic voltammogram shows Ru(III)- Ru(II) couple alongwith ligand reductions.
