The title complex N,O-bis{2-[[(2-benzhydryl-4,6-dimethylphenyl)imino]-methyl]-phenol}-nickel(II)(C_(56)H_(48)N_2NiO_2) has been synthesized by the reaction of 2-[[(2-benzhydryl-4,6-dimethylphenyl)mino]-methyl]-phenol with Ni(CH_3COO)_2·4 H_2O, and characterized by elemental analysis and IR spectrum. The spatial structure of the complex has been confirmed by single-crystal X-ray diffraction analysis. The compound belongs to the monoclinic system, space group C2/c with a = 39.035(8), b = 13.276(3), c = 17.679(4) ?, β = 98.06(3)°, V = 9071(3) ?~3, C_(56)H_(48)N_2NiO_2, M_r = 839.67, Z = 8, D_c = 1.230 Mg/m~3, μ = 0.472 mm~(-1), F(000) = 3536, T = 293(2) K, the final R = 0.0675 and w R = 0.1345(I > 2s(I)). The compound showed excellent catalytic activity up to 1.268 × 10~7 g of PNB(mol of Ni)~(-1)h~(-1) for the addition polymerization of norbornene by using methylaluminoxane(MAO) as a cocatalyst.
