Four possible structures of C2-symmetric bis(fluorenyl)zirconium complexes are presented. Three bis(fluorenyl)zirconocene complexes have been prepared and tested for the polymerization of propylene and ethylene. rac / meso-Dichloro[η10-(1,2-ethanediyl)bis ( seems to be the most active polymerization catalysts for ethylene.
