The title complex bis{1-[[(3-methyl-pyridin-2-yl) amino] methyl-phenyl]-2-hydroxy-3,5-di-tert-butylphenol} palladium (C₄₂H₅₆O₂N₄Pd) 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 P with a = 12.3870(13), b = 12.9673(12), c = 14.3998(4) Å, α = 67.53(2), β = 75.34(2), γ = 86.89(3)°, V = 2065.5(3) Å³, M_r = 773.32, Z = 2, D_c = 1.243 g/cm³, 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 × 10⁷ g of PNB (mol of Pd)^-1 h^-1 with high monomer conversion using methylalumi-noxane (MAO) as the cocatalyst.
