摘　　要：The title complex bis{（2-benzhydryl-4,6-dimethyl-phenyl）-（3,5-di-tert-butyl-2-methyl-benzylidene）-amine-N,O}nickel has been synthesized by the reaction of（2-benzhydryl-4,6-dimethyl-phenyl）-（3,5-di-tert-butyl-2-methyl-benzylidene）-amine with Ni（CH3COO）2·4H2O, and characterized by IR spectrum and single-crystal X-ray diffraction analysis. The crystal belongs to the monoclinic system, space group P21/c with a = 12.373（4）, b = 18.434（7）, c = 27.814（10） A, β = 92.291（6）o, V = 6339（4） A^3, C7 2H8 0N2 Ni O2, Mr = 1064.09, Z = 4, Dc = 1.115 g/cm^3, μ = 0.350 mm^-1, F（000） = 2280, the final R = 0.0846 and wR = 0.2926（I 〉 2s（I））. This title compound was used as homogeneous catalysis of polymerization of norbornene, and the complex exhibited good catalytic activity to catalyze norbornene polymerization using MAO as a cocatalyst.The title complex bis{（2-benzhydryl-4,6-dimethyl-phenyl）-（3,5-di-tert-butyl-2-methyl-benzylidene）-amine-N,O}nickel has been synthesized by the reaction of（2-benzhydryl-4,6-dimethyl-phenyl）-（3,5-di-tert-butyl-2-methyl-benzylidene）-amine with Ni（CH3COO）2·4H2O, and characterized by IR spectrum and single-crystal X-ray diffraction analysis.
