3-Benzoyl-4-hydr-oxy-2H-1,2-benzothia-zine 1,1-dioxide.

ABSTRACT: There are two mol-ecules in the asymmetric unit of the title compound, C(15)H(11)NO(4)S. The heterocyclic thia-zine rings in both mol-ecules adopt half-chair conformations with the S and N atoms displaced by 0.455?(4) and 0.254?(4)?Å, respectively, in one mol-ecule, and 0.480?(4) and 0.224?(5)?Å in the other, on opposite sides of the mean planes formed by the remaining ring atoms. The crystal structure is stabilized by inter-molecular N-H?O and C-H?O hydrogen bonds. In addition, intra-molecular O-H?O inter-actions are also present.
