The asymmetric unit of the title compound, C23H19NO2S, contains two molecules that differ in the conformation of the two carboxamide moieties. In the crystal, intermolecular N-H center dot center dot center dot O hydrogen bonds link the molecules into chains propagating parallel to the c-axis direction. Between the molecules, weak C-H center dot center dot center dot pi(ring) interactions are present, whereas pi-pi interactions are not observed. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions to the crystal packing are from H center dot center dot center dot H (47.6%), H center dot center dot center dot C/C center dot center dot center dot H (33.4%) and H center dot center dot center dot O/O center dot center dot center dot H (11.6%) interactions. Orientational disorder is observed for both thiophene rings.
