The present invention relates to compounds according to formula I: wherein: each R1-R10 may individually be H, a halogen, an alkoxy moiety, a siloxy moiety, a nitrogen-containing moiety, an alkyl moiety, an aryl moiety, or an aralkyl moiety, wherein each R1-R10 comprises ≤10 carbon atoms, wherein each of R1-R10 may form a cyclic moiety with an adjacent R1-R10 moiety; Y is O or N—R11, wherein R11 is an alkyl, cycloalkyl, aryl or aralkyl moiety comprising 1-12 carbon atoms; M is a group 3 or 4 transition metal; X is a sigma-bonded ligand, or a diene; z is the number of ligands X that are bonded to M. Such compounds may be used in a catalyst system for olefin polymerisation.
