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.
在标题化合物C(9)H(7)N(2)O(2)S(+)·C(7)H(5)O(6)S(-)·2H(2)O的晶体结构中,一个来自5-磺基水杨酸的氢原子转移到吡啶氮原子上,形成一种盐。噻唑环和吡啶鎓环之间的二面角为5.909 (5)°。晶体堆积由涉及水分子的O-H⋯O和N-H⋯O氢键决定。
