4-Hy­droxy-2-methyl-1,1-dioxo-2H-1λ(6),2- benzothia­zine-3-carb­oxy­lic acid hemihydrate

In the title compound, C(10)H(9)NO(5)S·0.5H(2)O, two geometrically different organic mol­ecules are present. The benzene rings and the carboxyl­ate groups are oriented at dihedral angles of 13.44 (4) and 21.15 (18)°. In both mol­ecules, an intra­molecular O—H⋯O hydrogen bond generates an S(6) ring....

Sumario:In the title compound, C(10)H(9)NO(5)S·0.5H(2)O, two geometrically different organic mol­ecules are present. The benzene rings and the carboxyl­ate groups are oriented at dihedral angles of 13.44 (4) and 21.15 (18)°. In both mol­ecules, an intra­molecular O—H⋯O hydrogen bond generates an S(6) ring. In the crystal, both moleucles form inversion dimers linked by pairs of O—H⋯O hydrogen bonds to generate R (2) (2)(8) loops. The dimers are consolidated into chains extending along [100] by bridging O—H⋯O hydrogen bonds from the water mol­ecule. A weak C—H⋯O hydrogen bond also occurs.
