Abstract:
The title compound, (C(12)H(10)BrFN)[Ni(C(3)S(5))(2)], is an ion-pair complex consisting of N-(2-fluoro-4-bromo-benz-yl)pyridinium cations and [Ni(dmit)(2)](-) anions (dmit = 2-thioxo-1,3-dithiole-4,5-dithiol-ate). In the anion, the Ni(III) ion exhibits a square-planar coordination involving four S atoms from two dmit ligands. In the crystal structure, weak S⋯S [3.474 (3), 3.478 (3) and 3.547 (3) Å] and S⋯π [S⋯centroid distances = 3.360 (3), 3.378 (2), 3.537 (2) and 3.681 (3) Å] inter-actions and C-H⋯F hydrogen bonds lead to a three-dimensional supra-molecular network.

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,...
