abstraction of water from the solvents. The solid structures of (1,3-Me2C5H2−CHPh−NtBu−κN)Zr(NMe2)2, 10, 11, and 12 have been determined by X-ray crystallography. The complexes are active towards the polymerization of ethylene when activated with MAO. The activities are rather low and the molecular weight distributions are broad (Mw/Mn = 10−36).
