Abstract
In the title molecule, C16H14N2O4S, the thiazine ring adopts a twist chair conformation with the N and adjacent C atom displaced by 0.966 (3) and 0.386 (4) Å, respectively, on the same side of the mean plane formed by the remaining ring atoms. The dihedral angle between the mean planes of the benzene rings is 37.65 (10)°. The molecular structure features an intramolecular O—H⋯O hydrogen bond, which generates an S(6) ring. In the crystal, molecules are linked by N—H⋯O and C—H⋯O hydrogen bonds.
