In the title compound, C18H12ClNOS, the thiazine-3-one ring of the 1,4-thiazin-3-one moiety adopts a slightly distorted twist-boat conformation. The dihedral angle between the benzene rings is 86.2 (1)°. In the crystal, the crystal packing features a single weak C—H...O interaction and weak π–π stacking interactions.
