Abstract
In the title compound, C17H12F3NO4S, the heterocyclic thiazine ring adopts a half-chair conformation with the S and the N atoms displaced by −0.608 (3) and 0.105 (3) Å, respectively, from the mean plane formed by the remaining ring atoms. The dihedral angle between the two benzene rings is 36.63 (8)° and the acetic acid group is inclined at right angles [89.78 (8) °] to the mean plane formed by the C atoms of the thiazine ring. The crystal structure features O—H⋯O and C—H⋯O hydrogen bonds.
