The complexes of N,N-bis(benzimidazol-2-ylmethyl) amine with zinc (Ⅱ ), C16H15N5Zn·(ClO4)2·3H2O (A) and C32H30N10Zn·(ClO4)2·C2H5OH (B), were synthesized and characterized with element analysis, UV, and IR spectroscopy. The crystal structure of (B) was determined by X-ray diffraction. Quantum chemistry computation was also performed on the these compounds using G94W program. Biological activities of the complexes were measured by means of pyrogallo autoxidation.

Key words: BENZIMIDAZOLE P, PROPANAMINE P, SUPEROXIDE DISMUTASE, QUANTUM CHEMISTRY, ZINC COMPLEX, CRYSTAL STRUCTURE, ELECTRONIC STRUCTURE, BIOLOGICAL ACTIVITY
