Methyl 4-hydr-oxy-2H-1,2-benzothia-zine-3-carboxyl-ate 1,1-dioxide.

ABSTRACT: The asymmetric unit of the title compound, C(10)H(9)NO(5)S, contains two independent mol-ecules. The heterocyclic thia-zine rings in both mol-ecules adopt half-chair conformations, with the S atoms in each mol-ecule displaced by 0.455?(3) and 0.539?(3)?Å and the N atoms displaced in the opposite direction by 0.214?(3) and 0.203?(3)?Å, from the planes defined by the remaining ring atoms. The crystal structure is stabilized by O-H?O, N-H?O and C-H?O hydrogen bonds involving both inter- and intra-molecular inter-actions.
