摘　　要：报导了对称的十齿配体Ｎ，Ｎ，Ｎ′，Ｎ＂，Ｎ，Ｎ－六（２′－甲基苯并咪唑基）三乙四胺（ＴＴＨＢ）及该配体与Ｎｉ（Ⅱ）盐形成的三种多核配合物的合成及性质，包括元素分析，摩尔电导、红外、电子光谱、热分析及活性，结果表明：三种配合物中Ｎｉ（Ⅱ）分别为五配位及六配位，其构型接近四方锥和八面体。而这些配合物也能催化歧化Ｏ－２。A series of new multinuclear Ni(Ⅱ) complexes have been synthesized and characterized by element analyses、infrared spectra、electronic spectra、conductivity and thermogravimetric analyses.The results suggest that the nitrate of Ni(Ⅱ) is easy to form binuclear complexes,and the chloride of Ni(Ⅱ) is easy to form binuclear and trinuclear complexes with TTHB.The Ligand coordinates to Ni(Ⅱ) through its benzimidazolyl N 3′ and its tert-amine N.In all these complexes,Ni(Ⅱ) was five coordinated and six coordinated respectively.
