    Abstract: Metal complexes useful as olefin polymerization ccatalysts corresponding to formula (I) or a dimer, solvated adduct, chelated derivative or mixture thereof, wherein L is a cyclic group or Y, that is bound to M by means of a delocalized π-bond, said group containing up to 50 non-hydrogen atoms; M is a metal of Group 3, 4 or the Lanthanide serie of the Periodic Table of the Elements; Z is a covalently bound, divalent substituent of up to 50 non-hydrogen atoms having the formula: -(ER2)m-, wherein E independently each occurrence is carbon, silicon or germanium, R independently each occurrence is selected from the group consisting of hydrocarbyl, hydrocarbyloxy, silyl, and germyl of up to 20 atoms other than hydrogen, and m is an integer from 1 to 3; Y is an allyl or hydrocarbyl-, silyl- or germyl-substituted allyl group containing up to 20 non-hydrogen atoms bonded to Z and bonded via an θ3-π bond to M; X' is a neutral ligand having up to 20 non-hydrogen atoms; X' independently each occurrence is a monovalent, anionic moiety selected from hydride, halo, hydrocarbyl, silyl, germyl, hydrocarbyloxy, amide, siloxy, halohydrocarbyl, halosilyl, silylhydrocarbyl, and aminohydrocarbyl having up to 20 non-hydrogen atoms, or two X' groups together form a divalent hydrocarbadiyl group; n is a number from 0 to 3; and p is an integer from 0 to 2.
