Abstract: Catalyst compositions include a reduced transition metal complex of structure (I) and a cocatalyst. where, L1 and L2, may be the same or different, are anionic ligands, other than cyclopentadienyl group, amido group or phosphidino group. At least L1 is able to non-covalently interact with reduced transition metal M via one or more functional groups; for example, L1 can be a phenyl group in which at least one of the ortho-positions is substituted with a functional group capable of donating electron density to the transition metal M. L1 can also be a methyl group in which one or more or the alpha-positions is substituted with a functional group capable of donating electron density to the transition metal M. X, K, and m are defined in the specification. These catalysts may be easily formed as solids and provide improved catalytic performance.
