Pyrazine-diium bis-(3-carb-oxy-4-hydroxy-benzene-sulfonate) dihydrate.

ABSTRACT: Pyrazine and 5-sulfosalicylic acid crystallize from a methanol solution containing water as the title salt, C(4)H(6)N(2) (2+)·2C(7)H(5)O(6)S(-)·2H(2)O. The pyrazine-diium cation sits on an inversion center. The component ions and water mol-ecules are linked by inter-molecular O-H?O, N-H?O and C-H?O hydrogen bonds into layers running parallel to the (10) plane.
