N-Benzyl-4-hydroxy-2-methyl-1,1-dioxo2H-1 lambda(6),2-benzothiazine-3-carboxamide

In the title molecule, C17H16N2O4S, the heterocyclic thiazine ring adopts a half-chair conformation, with the S and N atoms displaced by 0.546 (4) and 0.281 (4)angstrom, respectively, on opposite sides of the mean plane formed by the remaining ring atoms. The molecular structure is stabilized by an intramolecular O-H center dot center dot center dot O hydrogen bond. The two aromatic rings are inclined to one another by 42.32 (11)degrees. In the crystal, molecules are linked by pairs of N-H center dot center dot center dot O hydrogen bonds, forming inversion dimers. The dimers are linked via a series of C-H center dot center dot center dot O interactions, leading to the formation of a threedimensional network.
