title: 3-(4-Methoxybenzyl)-1,5-benzo-thiazepin-4(5H)-one.
abstract: In the title compound, C17H15NO2S, the thia-zepine ring adopts a slightly distorted twist-boat conformation. The dihedral angle between the mean plane of the benzo-thia-zepin ring system and the benzene ring is 65.7 (1)°. In the crystal, pairs of N-H⋯O hydrogen bonds link inversion-related mol-ecules into dimers, generating R2 (2) (8) ring motifs. These dimers are further linked by C-H⋯π and π-π inter-actions [inter-centroid distance between the benzene rings of the benzo-thia-zepine unit = 3.656 (3) Å] into a three-dimensional supra-molecular network.
