Bis(?5-cyclopentadienyl)bis(2,4,6-trimethylphenyltellurolato)zirconium(IV)
The structure of the title compound, [Zr(C5H5)2(C9H11Te)2], consists of a zirconium(IV) centre bonded to two 5-coordinated cyclopentadienyl groups and two mesityltellurolate ligands; the discrete molecule has crystallographic twofold rotation symmetry. The structural parameters compared with those in [(5-Me5Cp)2Zr(TePh)2] [Howard, Trnka & Parkin (1995). Inorg. Chem. 34, 5900-5909] show that the greater steric demands of the bulky mesityl substituents are accommodated by widening Te-Zr-Te (8°) and by more acute Zr-Te-C (5°) angles, although the Zr-Te distances are essentially the same. The crystal studied exhibited some inversion twinning.

Abstract
The structure of the title compound, [Zr(C5H5)2(C9H11Te)2], consists of a zirconium(IV) centre bonded to two 5-coordinated cyclopentadienyl groups and two mesityltellurolate ligands; the discrete molecule has crystallographic twofold rotation symmetry. The structural parameters compared with those in [(5-Me5Cp)2Zr(TePh)2] [Howard, Trnka & Parkin (1995). Inorg. Chem. 34, 5900-5909] show that the greater steric demands of the bulky mesityl substituents are accommodated by widening Te-Zr-Te (8°) and by more acute Zr-Te-C (5°) angles, although the Zr-Te distances are essentially the same. The crystal studied exhibited some inversion twinning.
