1-(4-Chlorophenyl)-2-[4-hydroxy-3-(3-methoxybenzoyl)-1,1-dioxo-2H-1λ6,2-benzothiazin-2-yl]ethanone

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.
