Abstract: In the title compound, C17H15NO2S, the thiazepine ring adopts a slightly distorted twist-boat conformation. The dihedral angle between the mean plane of the benzothiazepin ring system and the benzene ring is 65.7 (1)°. In the crystal, pairs of N-H...O hydrogen bonds link inversion-related molecules into dimers, generating R22(8) ring motifs. These dimers are further linked by C-H...[pi] and [pi]-[pi] interactions [inter-centroid distance between the benzene rings of the benzothiazepine unit = 3.656 (3) Å] into a three-dimensional supramolecular network.
