“…A wide range of nickel complexes are known to exhibit an antioxidant and antimicrobial activity against the several microorganisms [25,26]. The nickel complexes of 1,10-phenanthroline (phen) and 2,2 0 -bipyridine (bpy) derivatives have shown the binding and cleavage of DNA residues [27][28][29][30][31]. Thus tuning the properties of metal complexes using an appropriate nonheme ligand architecture has become an art for the inorganic chemist from the days of Alfred Werner.…”
