Abstract: The present invention relates to a A metal complex of formula 1 CyYMLjXn  (formula 1) wherein Cy is a cyclopentadienyl-type ligand; M is a metal of group 4; L is a neutral Lewis basic ligand wherein the number of said neutral ligands “j” is in the range of 0 to the amount that satisfies the 18-electron rule: X is an anionic ligand; n is an integer denoting the number of anionic ligands X and is 1 or 2, preferably is 2; Y is a cyclic amidine-containing ligand moiety represented by formula 2 wherein the amidine-containing ligand is covalently bonded to the metal M via the imine nitrogen atom N2; S is a —CH2— unit, and t is the integer number denoting the number of S and is in the range of 1-4, more preferably in the range of 1-2, most preferably is 1; Sub1 is an aliphatic cyclic or linear substituent comprising a group 14 atom through which Sub2 is bonded to the amine nitrogen atom N1; Sub2 is an optionally substituted C2 unit in which the 2 carbon atoms may be sp2 or sp3 hybridized.
