(Z)-3-(4-Chlorobenzyl)-1,5-benzothiazepin-4(5H)-one

Abstract

In the title compound, C16H12ClNOS, the seven-membered thiazepine ring adopts a distorted twisted boat conformation. The dihedral angle between the least-squares planes of the 1,5-benzothiazepine ring system and the benzene ring is 50.2 (1)°. In the crystal, pairs of N—H...O hydrogen bonds link centrosymmetrically related molecules into dimers, generating R22(8) ring motifs. The crystal packing is further stabilized by π–π interactions [centroid–centroid distance = 3.763 (2) Å].
