Three new metal complexes, namely: [Mn(AIDB)Cl 2 ]·DMF (1) , [Zn(AIDB)Br 2 ]·CH 3 OH (2) and [Co(AIDB)Cl 2 ]·CH 3 OH (3) having a ligand bis(benzimidazol-2-ylmethyl)allylamine (AIDB), have been synthesized in high yields and characterized by elemental analyses, molar conductivities, IR, UV–Vis spectra and single-crystal X-ray diffraction. The structural analysis revealed that all the three complexes 1 – 3 have five-coordinated trigonal bipyramid geometry where the degree of distorting is 1>3>2 . In vitro antioxidant activity assay demonstrates that the complexes 1 and 3 display high scavenging activity against hydroxyl (OH·) and superoxide (O 2 −· ) radicals.
