| 摘 要： | The title complex bis{1-[[(3-ethyl-6-methyl-2-pyridinyl)imino]methylenyl]- 2-na- phthalenola-to-N,O}nickel has been synthesized by the reaction of 1-[[(3-ethyl-6-methyl-2- pyridinyl) imino] methylenyl]-2-naphthalenol with Ni(CH3 COO)2 ·4H2 O, and characterized by IR spectrum and single-crystal X-ray diffraction analysis. The crystal belongs to the orthorhombic system, space group Pbca with a = 11.100(2), b = 15.900(3), c = 18.000(4), V = 3176.8(11)3, C38 H34 N4 NiO2, Mr = 637.40, Z = 4, Dc = 1.333 g/cm3, μ = 0.651 mm-1, F(000) = 1336, the final R = 0.0783 and wR = 0.2119. This title compound was investigated for the catalytic behavior towards norbornene(NB) vinyl addition polymerization. And the complex exhibited good catalytic activity to catalyze norbornene polymerization using MAO as a cocatalyst.
