Reaction of 5-sulfosalicylic acid with hydrazine hydrate at pH = 1 results in the formation of the title hydrated salt, 0.5N(2)H(6) (2+)·C(7)H(5)O(6)S(-)·2H(2)O. The hydrazinium dications lie on centres of inversion. They are located between 3-carb-oxy-4-hy-droxy-benzene-sulfonate anions, forming inter-molecular N-H⋯O hydrogen bonds with sulfonate ions and water mol-ecules of crystallisation. Further intra- and inter-molecular O-H⋯O hydrogen bonds are observed in the crystal structure.
在pH = 1的条件下，5-磺基水杨酸与水合肼反应生成标题水合盐0.5N(2)H(6) (2+)·C(7)H(5)O(6)S(-)·2H(2)O。肼鎓二价阳离子位于对称中心上。它们位于3-羧基-4-羟基苯磺酸盐阴离子之间，与磺酸根离子和结晶水分子形成分子间N-H⋯O氢键。在晶体结构中还观察到进一步的分子内和分子间O-H⋯O氢键。
