    Abstract: The present application provides a catalyst component for alkene polymerization. The catalyst component contains: (a) a group 4 transition metal or rare earth metal, (b) a rigid non-cyclopentadienyl ligand with a tricyclic backbone composed of three ortho -fused 6-membered rings in a linear arrangement (as is the case in xanthene), with or without additional fused rings; the tricyclic backbone contains at least one donor atom within the central ring (as is the case for xanthene, oxanthrene, or acridan); furthermore, donor atoms/groups or aryl rings are attached directly (i.e. via the donor atom in the case of donor groups) to both of the bondable carbon atoms adjacent to at least one of the donor atoms within the central ring (e.g. xanthene with two donor groups, or two aryl rings, or one donor group and one aryl ring adjacent to oxygen), and (c) two or more activatable ligands, such as chloro, alkyl, aryl, allyl or hydride ligands, attached to the central metal if the complex is neutral or anionic, or one or more activatable ligand if the complex is monocationic or dicationic. The rigid non-cyclopentadienyl ligand has a charge of 0, 1– or 2– (considering all donor atoms of the ligand to have an octet of valence electrons). The catalyst component is optionally combined with an activator, typically for the purpose of generating a highly active monocationic or dicationic polymerization catalyst, and the catalyst and/or catalyst components may be in solution, precipitated from solution, or optionally carried on a support.
