An unbridged zirconocene complex bis(1,2-diphenylcyclopentadienyl)zirconium dichloride[(1,2-Ph₂-C₅H₃)₂ZrCl₂] 1 has been synthesized and structurally characterized. When activated by MAO, 1 produces ultra-high molecular weight polyethylene with high melting transition temperature, as well as atactic oligopropylene with average molecular weight of ~1150 g mol^-1.
