چکیده
In the title compound, C15H13NS, the thia-zine ring adopts a boat conformation. The dihedral angle between the planes of the benzene ring of the benzo-thia-zine unit and the tolyl ring is 19.52 (9)°. In the crystal, mol-ecules are linked by weak C-H⋯π inter-actions into a tape structure along the b-axis direction.
