S. Gao, L.-H. Huo and S. W. Ng

Abstract: The cation, anion and water molecules of the title compound, 2C₅H₆NO⁺·C₁₀H₆O₆S₂^2-·2H₂O, interact via hydrogen bonds, giving rise to a tight three-dimensional network structure. Two independent anions both lie on centers of inversion, and the asymmetric unit consists of two half-anions, two independent cations and two independent water molecules.
