2-[2-(3-Chloro­phen­yl)-2-oxoeth­yl]-4-hy­droxy-3-(3-meth­oxy­benzo­yl)-2H-1λ(6),2-benzothia­zine-1,1-dione

In the title mol­ecule, C(24)H(18)ClNO(6)S, the heterocyclic thia­zine ring adopts a half chair conformation with the S and N atoms displaced by 0.318 (3) and 0.387 (3) Å, respectively, on the opposite sides from the mean plane formed by the remaining ring atoms. The benzene rings of the benzothia­zin unit and meth­oxy­benzoyl group are more or less coplanar, the dihedral angle between the mean planes of these rings being 12.37 (10)° while the chloro­phenyl ring is inclined at 81.87 (4) and 73.30 (5)°, respectively, to these rings. The mol­ecular structure is consolidated by intra­molecular O—H⋯O and C—H⋯N inter­actions and the crystal packing is stabilized by weak inter­molecular C—H⋯O hydrogen bonds.
