In the central part of the molecule, the amide and thioamide residues are approximately perpendicular [C - N - C - S torsion angle = -104.98 (18)°]. Supramolecular layers with a zigzag topology are formed in the crystal packing by N - H...O, N - H...S and C - H...O interactions; these stack along c, being separated by hydrophobic interactions.enArticle
