Abstract: | The title compound, Zr(C7H7)3(C15H17)], (I), crystallizes from light petroleum with two independent molecules in the asymmetric unit. Whereas in the parent molecule, Zr(η5‐C5H5)(CH2Ph)3, all three Zr—CH2Ph angles are equal, in (I), they differ significantly. In spite of their different environments, both independent molecules in (I) exhibit a small, an expected, and a large Zr—CH2Ph angle. The angles are similar to those of the closely related tribenzylη5‐(benzyldimethylsilyl)cyclopentadienyl]zirconium complex. The smallest Zr—CH2Ph angle and the consequently relatively short Zr?Cipso distance are indicative of η2‐bonding of the benzyl group. |
