摘要
The crystal structure of the title compound, [Hf(C10H15)(2)(C4H9)(2)], reveals two independent molecules in the asymmetric unit. The diffraction experiment was performed with a racemically twinned crystal showing a 0.529 (5): 0.471 (5) component ratio. Each Hf-IV atom is coordinated by two pentamethylcyclopentadienyl and two n-butyl ligands in a distorted tetrahedral geometry, with the cyclopentadienyl rings inclined to one another by 45.11 (15) and 45.37 (16)degrees. In contrast to the isostructural di(n-butyl)bis-(eta(5)-pentamethylcyclopentadienyl)zirconium(IV) complex with a noticeable difference in the Zr-butyl bonding, the Hf-C-butyl bond lengths differ from each other by no more than 0.039 (3) angstrom.
