Abstract:
The asymmetric unit of the title hybrid compound, (C9H8N)[FeCl4]Cl, comprises a tetra-hedral tetra-chlorido-ferrate(III) anion, [FeCl4](-), a Cl(-) anion and two quinolinium cations. There are N-H⋯Cl hydrogen-bonding inter-actions between the protonated N atoms of the quinolinium cations and the chloride anion, which together with π-π stacking between adjacent quinolinium rings [centroid-to-centroid distances between C6 and C5N rings in adjacent stacked quinolinium cations of 3.609 (2) and 3.802 (2) Å] serve to hold the structure together.

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...
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,...
Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
