Abstract
The title compound,bromo-(2-diphenylphosphino-N-(2-oxybenzylidene)-aniline)- nickel,was synthesized by simple condensation of 2-diphenylphosphino-N-(2-oxybenzylidene)- aniline with NiBr2·6H2O and characterized by elemental analysis,IR spectra and single-crystal X-ray diffraction. The crystal belongs to the triclinic system,space group P1 with a = 9.756(2),b = 10.232(2),c = 13.313(3) ,α = 95.09(3),β = 102.48(3),γ = 95.45(3)o,V = 1283.5(4) 3,C29H23BrNNiO2P,Mr = 587.07,Z = 2,Dc = 1.519 g/cm3,λ(MoKα) = 0.71073 ,F(000) = 596 and μ = 2.402 mm-1. The structure was refined to the final R = 0.0408 and wR = 0.0965 for 4507 observed reflections (I > 2σ(I)). Intermolecular π-π interactions (with distances of about 3.705 ) are pronounced in the crystal structure. Under methylaluminoxane (MAO) activation,the title com- pound was able to catalyze norbornene polymerization,exhibiting good polymerization activities.
