Abstract:
In the title compound, the hydrated tetra-(nitrate) salt of dapsone (4,4'-di-amino-diphenyl-sulfone), 2C12H14N2O2S2+·4NO3-·H2O {alternative name: bis[bis-(4,4'-di-aza-niumylphen-yl) sulfone] tetra-nitrate monohydrate}, the cations are conformationally similar, with comparable dihedral angles between the two benzene rings in each of 70.03 (18) and 69.69 (19)°. In the crystal, mixed cation-anion-water mol-ecule layers lying parallel to the (001) plane are formed through N-H⋯O, O-H⋯O and C-H⋯O hydrogen-bonding inter-actions and these layers are further extended into an overall three-dimensional supra-molecular network structure. Inter-ring π-π inter-actions are also present [minimum ring centroid separation = 3.693 (3) Å].

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,...
