Three novel mixed ligand M(II) complexes, namely [CoL1 L2 Cl2 ] ( 1 ), [CuL1 L2 Cl2 ] ( 2 ), and [ZnL1 L2 Cl2 ] ( 3 ), were synthesized using 1,4-naphthoquinone, L-histidine, and 1,10-phenanthroline as ligands. The ligand framework and the corresponding structural changes on complexation were ascertained based on the results of elemental analysis, conductivity measurements, magnetic behavior, FT-IR, UV-visible, 1 H NMR, 13 C NMR, ESR spectral studies, and ESI mass spectrometry. The biological action of the ligand ( L ) and complexes 1 - 3 such as DNA binding and cleaving ability were studied...
