Abstract:	Three new metal complexes, namely: Mn(AIDB)Cl₂]·DMF (1), Zn(AIDB)Br₂]·CH₃OH (2) and Co(AIDB)Cl₂]·CH₃OH (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 (O₂^−·) radicals.
