Abstract:
The reaction of ZrCl4 with three equivalents of LiNCy2 (Cy is cyclo-hex-yl) resulted in the formation of tris-(di-cyclo-hexyl-amido)-zirconium chloride and the title compound, [Zr(C12H22N)4]. The latter is isotypic with its cerium(IV) analogue and crystallizes with three independent mol-ecules in the asymmetric unit. One mol-ecule is located about a twofold rotation axis, and the other two on fourfold inversion axes. In each mol-ecule, the ZrIV atom has a distorted tetra-hedral coordination environment. The crystal under investigation was twinned by inversion in a 1:1 ratio.

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,...
Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
