【 摘 要 】

In the racemic title compound, C20H15NO2S, the planes of the two phenyl substituents form dihedral angles of 48.97 (15) and 69.26 (15)° with that of the fused benzene ring of the parent benzo­thia­zine ring, while the heterocyclic thia­zine ring exhibits a screw-boat pucker. The O atom on the S atom of the ring is pseudo-axial on the thia­zine ring and trans to the 2-phenyl group. In the crystal, mol­ecules are arranged in layers in the ac plane, the layers being linked across b through inter­molecular C—H⋯O hydrogen-bonding inter­actions.
