Abstract:
The title compound, C13H10N2O7S, was synthesized via a nucleophilic substitution reaction between 2,4-di-nitro-phenol and p-toluene-sulfonyl chloride. This crystal structure is a polymorph of CSD entry WUVYUH [Vembu et al. (2003). Acta Cryst, E59, o378-380]. The aromatic substituents on the sulfonate group are oriented gauche to one another with a C-O-S-C torsion angle of -62.0 (3)°. The supra-molecular features that contribute to the crystal stability are offset π-π [centroid-centroid distance = 3.729 (2) Å] and multiple C-H⋯O inter-actions.

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...
