The steric and electronicinfluence of various substituents at different positions of the fluorenylidene fragment effects the catalytical properties of the MAO activated bis(fluorenylidene) complexes [C13H8−nRn(CH2)2C13H8−nRn]ZrCl2 (n=0–2; R=H, alkyl, aryl, (CH)4, OCH3). We report the synthesis and characterization of 27 new ansa bis(fluorenylidene) zirconium dichloride complexes and illustrate
