Crystal structure of (1,3-di-tert-butyl-η5-cyclopentadienyl)trimethylhafnium(IV)

Abstract

The molecule of the title organometallic hafnium(IV) compound, [Hf(CH3)3(C13H21)] or [HfMe3(η5-C5H3-1,3-tBu2)], adopts the classical three-legged piano-stool geometry for monocyclopentadienylhafnium(IV) derivatives with the three methyl groups bonded to the Hf(IV) atom at the legs. The C atoms of the two tert-butyl group bonded to the cyclopentadienyl (Cp) ring are 0.132 (5) and 0.154 (6) Å above the Cp least-squares plane. There are no significant intermolecular interactions present between the molecules in the crystal structure.
