Mn(II) complex with orthohydroxypropiophenoneisonicotinoylhydrazone has been synthesized. The structural features and other properties were deduced from the IR, Electronic, EPR spectra and powder X-ray diffraction (XRD) techniques. The Electronic spectrum exhibits various bands which were characteristic of Mn(II) in distorted octahedral site symmetry. The Powder X-ray diffraction patterns of the complex have indexed to monoclinic system. The ligand and Mn(II) complex have been tested for in vitro antibacterial and antioxidant activities. Molecular docking experiments were conducted to evaluate the inhibitory activities of ligand and its Mn(II) complex against DNA. The results reveal that the Mn(II) complex shows more activity than the free ligand and the binding energy of docked ligand and Mn(II) complex were found to be -6.9 and -7.4Kcal mol−1, respectively. The more negative relative binding energy of Mn(II) complex suggests greater interaction with DNA than the ligand.
