摘要

In the crystal structure of the title compound, C9H7N2O2S+center dot-C7H5O6S+center dot-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)degrees. The crystal packing is determined by O-H...O and N-H...O hydrogen bonds involving water molecules.
