ABSTRACT

New ruthenium(II) complexes with hydrazone ligand and 4-Bromo benzoic acid (2-hydroxy-1-naphthylidene) hydrazide (1) were synthesized. Structural features of the ligand and complexes were determined by various physicochemical and spectral techniques. The hydrazone ligand acts as tridendate ligand with ONO as the donor sites and is preferably found in the enol form in the complexes. The radical scavenging ability, assessed using a series of antioxidant assays involving 2,2-diphenyl-2-picrylhydrazyl radical, hydroxyl radical, and nitric oxide radical, showed that the complexes possess significant radical scavenging activity.

Key words: Hydrazone, Ru(II)complexes, Spectral studies, Antioxidant
