A series of new nickel complexes NiCl 2 (L) based on tridentate NZN ligands (1, L = bis[2-(3,5dimethyl-pyrazolyl) has been prepared and characterized by elemental analysis. Upon activation with methylaluminoxane (MAO) or diethylaluminum chloride (DEAC), these new pre-catalysts show high activity in
