The N,N'-(phenyl-2-pyridinylmethylene)-3,3',5,5'-tetramethylbenzidine and its dimeric Co(II) and Ni(II) complexes were synthesized.The organic compound was characterized by elemental analyses,IR and NMR spectra,while the bimetal complexes were determined by elemental analyses,IR spectra as well as the single-crystal X-ray diffraction.The nickel complex showed high activity for ethylene polymerization and its cobalt analogue showed negligible active in ethylene activation. |
