2-(3-Benzoyl-4-hy-droxy-1,1-dioxo-2H-1?,2-benzothia-zin-2-yl)-1-phenyl-ethanone.

ABSTRACT: In the title mol-ecule, C(23)H(17)NO(5)S, the heterocyclic thia-zine 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(thia-zine)-C=O and O=C-CH(2) 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-H?O hydrogen bonds and further consolidated by C-H?? inter-actions; an intra-molecular O-H?O hydrogen bond is also present.
