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.

Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...
Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...
