摘要：The title complex N,O-bis{2-[[(2,6-benzhydryl-4-methylphenyl)imino]-methyl]- phenol}-pal 1 adium(II)(C8oH64N202Pd) has been synthesized by the reaction of 2-[[(2,6-benzhydryl- 4-methylphenyl)imino]-methyl]-phenol with Pd(CH3COO)2, and characterized by IR spectrum and elemental analysis. The spatial structure of the complex has been verified by single-crystal X-ray diffraction analysis. The compound belongs to the monoclinic system, space group P21/n with α= 13.492(3),b= 16.924(3), c= 14.135(3) A,β= 97.84(3)°, V=3197.4(11) A^3, C80H64N2O2Pd, Mr = 1191.73, Z = 2, Dc = 1.238 Mg/m^3,μ= 0.339 mm^-1, F(000)= 1240, T = 293(2) K, the final R = 0.0593 and wR = 0.1192 (I>2σ(I)). The compound showed excellent catalytic activity up to 1.130×10^7g of PNB (mol of Pd)^-1h^-1 for the addition polymerization of norbomene by using methylaluminoxane (MAO) as a cocatalyst.
