Abstract:

The structure of the title compound, [Zr(C(5)H(5))(2)(C(9)H(11)Te)(2)], consists of a zirconium(IV) centre bonded to two η(5)-coord-inated cyclo-penta-dienyl groups and two mesityltellurolate ligands; the discrete mol-ecule has crystallographic twofold rotation symmetry. The structural parameters compared with those in [(η(5)-Me(5)Cp)(2)Zr(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.
