摘　　要：The title complex bis{1-[[（3-methyl-pyridin-2-yl） amino] methyl-phenyl]-2-hydroxy-3,5-di-tert-butylphenol} palladium（C_（42）H_（56）O_2N_4Pd） has been synthesized by the reaction of 1-[[（3-methyl-pyridin-2-yl）amino]methyl-phenyl]-2-hydroxy-3,5-di-tert-butylphenol with Pd（OAc）_2, and was characterized by IR and elemental analyses（C, H, N）. Single-crystal X-ray diffraction analysis of the complex revealed an almost parallelogram geometry of the metal center, space group P1 with a = 12.3870（13）, b = 12.9673（12）, c = 14.3998（4） ？, α = 67.53（2）, β = 75.34（2）, γ = 86.89（3）°, V = 2065.5（3） A3, M_r = 773.32, Z = 2, D_c = 1.243 g/cm^3, μ = 0.489 mm^（-1）, F（000） = 816, the final R = 0.0649 and wR = 0.1567. The compound was investigated for the catalytic behavior towards norbornene（NB） vinyl addition polymerization. And the complex exhibits high catalytic activities up to 1.668 × 10~7 g of PNB（mol of Pd）^（-1） h^（-1） with high monomer conversion using methylaluminoxane（MAO） as the cocatalyst.The title complex bis{1-[[（3-methyl-pyridin-2-yl） amino] methyl-phenyl]-2-hydroxy-3,5-di-tert-butylphenol} palladium（C_（42）H_（56）O_2N_4Pd） has been synthesized by the reaction of 1-[[（3-methyl-pyridin-2-yl）amino]methyl-phenyl]-2-hydroxy-3,5-di-tert-butylphenol with Pd（OAc）_2, and was characterized by IR and elemental analyses（C, H, N）.
