Metal complexes useful as olefin polymerization catalysts corresponding to formula (I), wherein L is a delocalized, .pi.-bonded group that is bound to M, containing up to 50 nonhydrogen atoms; M is a metal of Group 3, 4 or the Lanthanide series 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 C1-20 hydrocarbyl, and C1-20 hydrocarbyloxy, with the proviso that in at least one occurrence R is C1-20 hydrocarbyloxy, and m is an integer from 1 to 3; Y is a divalent ligand group comprising nitrogen, phosphorus, oxygen or sulfur, said Y containing up to 20 nonhydrogen atoms; X' is a neutral Lewis base 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.

Complexes métalliques utiles comme catalyseurs de polymérisation d'oléfine, correspondant à la formule (I), où L est un groupe délocalisé à liaison .pi. lié à M et contenant jusqu'à 50 atomes autres que l'hydrogène; M est un métal du groupe 3, 4 ou de la série des lanthanides de la classification périodique des éléments; Z est un substituant bivalent lié par une liaison covalente, comprenant jusqu'à 50 atomes autres que l'hydrogène, de formule -(ER¿2?)¿m?-, où E est indépendamment carbone, silicium ou germanium, R est indépendamment choisi dans le groupe constitué de C¿1?-C¿20?-hydrocarbyle et C¿1?-C¿20?-hydrocarbyloxy, à condition que dans un cas au moins R soit C¿1?-C¿20?-hydrocarbyloxy et m un nombre entier compris entre 1 et 3; Y est un groupe ligand bivalent comprenant azote, phosphore, oxygène ou soufre, ledit Y contenant jusqu'à 20 atomes autres que l'hydrogène; X' est un ligand de base neutre de Lewis possédant jusqu'à 20 atomes autres que l'hydrogène; X" est un groupe anionique monovalent choisi indépendamment entre hydride, halo, hydrocarbyle, silyle, germyle, hydroxycarbyloxy, amide, siloxy, halohydrocarbyle, halosilyle, silylhydrocarbyle et aminohydrocarbyle possédant jusqu'à 20 atomes autres que l'hydrogène, ou deux groupes X" forment ensemble un groupe hydrocarbadiyle bivalent; n est un nombre compris entre 0 et 3; et p est un nombre entier compris entre 0 et 2.
