超氧化物歧化酶是一种金属酶，它具有防御机体内氧自由基损害的功能．它的活性中心是以咪唑桥联的多核过渡金属配合物［１～３］．人工合成以含苯并咪唑化合物为配体的单核、同双核配合物，无论是在理论上还是在实际应用中都有极其重要的意义．本文以三（２－苯并咪唑亚甲基）胺为配体，合成了其钴（Ⅱ）的配合物，并进行了元素分析，红外光谱分析及结构测定
Superoxide dismutase is a metalloenzyme that has the function of protecting against oxygen free radicals in the body. Its active center is based on imidazole bridged multi-core transition metal complexes [1-3]. Synthesized with monobenzimidazole compound as a ligand mononuclear, with binuclear complexes, both in theory and in practical applications are extremely important. In this paper, the complexes of cobalt (Ⅱ) were synthesized by using tris (2-benzimidazolylmethylene) amine as ligand, and elemental analysis, infrared spectrum analysis and structure determination
