2-[1,1-Dioxo-2-(2,4,5-trifluoro-benz-yl)-2H-1,2-benzothia-zin-4-yl]acetic acid.

ABSTRACT: In the title compound, C(17)H(12)F(3)NO(4)S, the heterocyclic thia-zine 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 thia-zine ring. The crystal structure features O-H⋯O and C-H⋯O hydrogen bonds.
