Abstract:
In the title compound, C17H17N O4S, the quinoline ring system is nearly planar, with a maximum deviation of 0.0496 (16) Å. A weak intra-molecular C-H⋯O inter-action is observed. In the crystal, C-H⋯O, S-H⋯N and π-π stacking inter-actions between the fused benzene ring of quinoline and the pyridine moieties [shortest centroid-centroid distance = 3.6754 (11) Å] are observed. Inversion-related weak C-H⋯O inter-molecular inter-actions diagonally along [010], with R 2 (2)(10) ring motifs, and S-H⋯N inter-molecular inter-actions diagonally along [100], with R 2 (2)(8) ring motifs, are present, forming a three-dimensional network structure. No classical hydrogen bonds are observed.

01:28Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the unhybridized p...
02:42Ionic 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...
02:46Crystal 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,...
