摘要
A novel salicylaldimine ligand and its mononuclear nickel complex [NiL]（L = 2-[[[2,6-bis（diphenylmethyl）-4-methylphenyl]imino]methyl]phenol） have been synthesized and characterized by IR spectrum, elemental analysis and thermogravimetry（TG）. The molecular structure of the complex has been measured by single-crystal X-ray diffraction analysis. The crystal belongs to the monoclinic system, space group P21/n with a = 13.281（3）, b = 16.938（3）, c = 13.981（3） ？, β = 97.03（3）o, V = 3121.2（11） A^3, C80H64N2O2Ni, Mr = 1144.04, Z = 2, Dc = 1.217 Mg/m^3, μ = 0.361 mm^-1, F（000） = 1204, the final R = 0.0582 and wR = 0.1108（I 〉 2s（I））. The compound showed excellent catalytic activity up to 12.78 × 10^6 g of PNB（polynorbornene）（mol of Ni）^-1 h^-1 for the addition polymerization of norbornene（NB） by using methylaluminoxane（MAO） as a cocatalyst.
