(2-Chlorophenyl)(4-hydroxy-1,1-dioxo-2H-1,2-benzothiazin-3-yl)methanone

Abstract

In the title molecule, C15H10ClNO4S, the heterocyclic thiazine ring adopts a half-chair conformation, with the S and N atoms displaced by 0.527 (7) and 0.216 (7) Å, respectively, on opposite sides of the mean plane formed by the remaining ring atoms. The molecular structure is consolidated by an intramolecular O—H...O interaction and the crystal packing is stabilized by N—H...O and C—H...O hydrogen bonds.
