6,2-benzothiazin-2-yl)-1-phenylethanoneAbstract: In the title molecule, C23H17NO5S, the heterocyclic thiazine ring adopts a half-chair conformation, with the S and N atoms displaced by 0.383 (3) and 0.473 (3) Å, respectively, on opposite sides of the mean plane formed by the ring C atoms. The phenyl rings attached to carbonyl groups lie almost parallel to each other at a dihedral angle 7.43 (9)°, the distance between the centroids of the rings being 3.780 (1) Å. The C(thiazine)-C=O and O=C-CH2 groups make dihedral angles of 37.56 (16) and 1.93 (18)°, respectively, with the phenyl groups to which they are attached. The crystal structure features O-H
O and C-HO hydrogen bonds and further consolidated by C-H![[pi]](/logos/entities/pi_rmgif.gif)
interactions; an intramolecular O-HO hydrogen bond is also present.
