Abstract:
1. A multinuclear catalyst complex comprising two or more active metal centres and at least one phenoxyimine derivative and at least one substituted cyclopentadienyl, indenyl or fluorenyl derivative, each phenoxyimine derivative being bonded to a cyclopentadienyl, indenyl or fluorenyl derivative forming a ligand framework, the cyclopentadienyl, indenyl or fluorenyl derivative being coordinated with one of the metal centres and the phenoxyimine derivative being coordinated with an active metal centre other than the metal centre the cyclopentadienyl, indenyl or fluorenyl derivative is coordinated with, and wherein the phenoxyimine derivative is derived from a phenoxyimine compound of the formula wherein R R R
