A metal complex of the formula (1)
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒCyAMX( L ) n €ƒ€ƒ€ƒ€ƒ€ƒ(1)
wherein
Cy is a cyclopentadienyl-type ligand,
M is a metal of group 4;
A is an 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, and Sub1 is a substituent comprising a group 14 atom through which Sub1 is bonded to the imine carbon atom and Sub2 is a substituent comprising a heteroatom of group 15, through which Sub2 is bonded to the imine carbon atom;
X is an allyl borate ligand derived from a conjugated diene ligand, D, and a borane, B and
L is a neutral Lewis basic ligand wherein the number of said metal ligands "n" is in the range of 1 to the amount that specifies the 18-electron rule. |
