摘　　要：Novel iron-based complex and ace- tyl(imino)pyridine iron(II) chloride (1 and 2) have been successfully synthesized and characterized. The behavior of the complex/methylaluminoxane (MAO) for ethylene polymerization was investigated and compared with 2,6-Bis(imino)pyridyl iron(II) chloride (3 and 4)/MAO. The results show that the new ace- tyl(imino)pyridine iron(II) chloride/MAO catalytic sys- tems were highly active for ethylene polymerization. Polyethylene from those polymerization systems has a bimodal molecular weight distribution (MWD).Abstract Novel iron-based complex and acetyl（imino）pyridine iron（Ⅱ） chloride （1 and 2） have been successfully synthesized and characterized.

The results show that the new acetyl（imino）pyridine iron（ll） chloride/MAO catalytic systems were highly active for ethylene polymerization.
