Crystal structure of 2-(4-methylphenyl)-4H-1,3-benzothiazine

Abstract

In the title compound, C15H13NS, the thiazine ring adopts a boat conformation. The dihedral angle between the planes of the benzene ring of the benzothiazine unit and the tolyl ring is 19.52 (9)°. In the crystal, molecules are linked by weak C—H...π interactions into a tape structure along the b-axis direction.
