Abstract:
The title salt, C(18)H(18)N(2) (2+)·2PF(6) (-), exists as non-inter-acting cations and anions. In the cation, the pyridine and phenyl-ene rings are aligned at 62.9 (1)°; the pyridine ring lies on a special position of m site symmetry and the phenyl-ene ring on a special position of 2/m site symmetry. The angle at the methyl-ene C atom is 112.8 (1)°. The anion lies on a special position of m site symmetry; four F atoms lie on this mirror plane.

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,...
