A new series of transition metal complexes with (1) Mn(III), (2) Co(II), (3) Ni(II) and (4) Cu(II) have been synthesized by the reaction of [ 6,60'-((1E, 1'E)( propane-1,3-diylbis(azanylylidene)) bis(methanylylidene)) bis(5-isopropyl-2-methylphenol)] with suitable metal salts. The synthesized complexes have been characterized by elemental analysis and spectroscopic techniques. The results of single crystal structures show that the metal is bonded to the ligand through the phenolic oxygens and imino nitrogens. Synthesized complexes have been evaluated for antibacterial activity and antioxidant activity, which shows considerable results.
