Unexpectedly high ethylene polymerisation activity is observed for zirconium(IV) catalysts supported by a rigid tridentate pyridine-bis(phenolate) ligand in conjunction with MAO; a methodology towards analogues with unsymmetricligands and the significance of the coordinated solvent molecule are described.
