4-(4-Carb-oxy-1,3-thia-zol-2-yl)pyridinium 3-carb-oxy-4-hydroxy-benzene-sulfonate dihydrate.

ABSTRACT: In the crystal structure of the title compound, C(9)H(7)N(2)O(2)S(+)·C(7)H(5)O(6)S(-)·2H(2)O, an H atom from the 5-sulfosalicylic acid is transferred to the pyridyl N atom, forming a salt. The dihedral angle between the thiazole and pyridinium rings is 5.909 (5)°. The crystal packing is determined by O-H⋯O and N-H⋯O hydrogen bonds involving water mol-ecules.
