Background:
- Understanding molecular configurations is crucial in organic chemistry.
- Crystal structure analysis provides insights into intermolecular forces and molecular arrangements.
Purpose of the Study:
- To elucidate the detailed three-dimensional structure of the title molecule, C(13)H(11)NO(4)S.
- To investigate the presence and implications of molecular disorder and hydrogen bonding within the crystal lattice.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- Analysis of bond lengths, bond angles, dihedral angles, and hydrogen bonding interactions.
Main Results:
- The molecule C(13)H(11)NO(4)S exhibits a trans configuration about the imine (C=N) double bond.
- Significant disorder was observed for the central benzene ring and the hydroxyl group, with distinct occupancy factors.
- Intra-molecular hydrogen bonding (O-H⋯N) and inter-molecular hydrogen bonding (O-H⋯O) forming chains along the a-axis were identified.
Conclusions:
- The crystal structure reveals specific geometric parameters and conformational preferences.
- Disorder in key functional groups impacts the overall molecular packing and symmetry.

Structures 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...
