A New Zirconocene Complex, [{η5-C5H4-C(CH2)5(CH2)2CH(CH3)2}2ZrCl2]

The title compound, dichlorobis­{η5-[1-(3-methylbutyl)cyclohex-1-yl]cyclopentadienyl}zirconium(IV), [ZrCl2(C16H25)2], has a pseudo-tetrahedral bent-metallocene structure in which the substituted cyclopentadienyl rings are asymmetrically bonded to the central Zr atom, due primarily to the interaction between the large substituents and the Cl atoms. The molecule has local C2 symmetry with the substituents positioned in a trans arrangement and directed towards the lateral sector of the bent-metallocene unit.
