Abstract:
The asymmetric unit of the title com-pound, C23H19NO2S, contains two mol-ecules that differ in the conformation of the two carb-ox-amide moieties. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains propagating parallel to the c-axis direction. Between the mol-ecules, weak C-H⋯π(ring) inter-actions are present, whereas π-π inter-actions are not observed. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions to the crystal packing are from H⋯H (47.6%), H⋯C/C⋯H (33.4%) and H⋯O/O⋯H (11.6%) inter-actions. Orientational disorder is observed for both thio-phene rings.

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...
