Abstract

In the title mol­ecule, C24H18ClNO6S, the heterocyclic thia­zine ring adopts a half-chair conformation with the S and N atoms displaced by 0.406 (5) and 0.444 (5) Å, respectively, on opposite sides of the mean plane formed by the remaining ring atoms. The meth­oxy­benzoyl and the chloro­phenyl rings lie roughly parallel to each other, with a dihedral angle between the mean planes of these rings of 8.86 (10)°. The mol­ecular structure is consolidated by intra­molecular O—H⋯O and C—H⋯O inter­actions and the crystal packing is stabilized by inter­molecular O—H⋯O and C—H⋯Cl hydrogen bonds.
