New group 4 organometallic complexes are characterized by having a phosphinimine ligand and two or more cyclopentadienyl ligands. Certain of these complexes exhibit unusual behavior when examined by nuclear magnetic resonance (NMR) techniques. Well defined crystals of the inventive complexes have been isolated and analyzed by x-ray crystallography. The complexes have also been found to be polymerization catalysts which are surprisingly more active than their simple metallocene analogs.
