Abstract:
The title mol-ecule, C(13)H(11)NO(4)S, displays a trans configuration with respect to the imine C=N double bond. The central benzene ring directly linked to N and the hydroxyl group are disordered over two orientations [occupancies of 0.510 (16)/0.490 (16) and 0.528 (8)/0.472 (8), respectively]. The dihedral angle between the two aromatic rings is 23.3 (5)° for the major component and 18.3 (5)° for the minor component. There is an intra-molecular O-H⋯N hydrogen bond and mol-ecules are linked into chains along the a axis by O-H⋯O hydrogen bonds.

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...
