A series of new cobalt and nickel complexes LMX2 (M = Co, X = Cl; M = Ni, X = Br) bearing 2, 6-bis(imino)phenoxy ligands were synthesized. The solid-state structures of 1 and 4 have been determined by single-crystal X-ray diffraction study. Treatment of the complexes LMX2 with methylalumninoxane (MAO) leads toa ctive catalysis for oligomerization of ethylene with catalysis activities in the range of 1.2 × 105-2.1 × 105 g mol-1 h-1 atm -1 for Ni complexes, and ～ 103 g mol-1 h-1 atm-1 for Co complexes. The oligomers were olefins from C4 to C16.
