In the crystal structure of the title salt, 3C(5)H(6)NO(+)·HSO(4) (-)·SO(4) (2-)·H(2)O, the hydrogen sulfate ion is linked to the sulfate ion by an O-H⋯O hydrogen bond. The hydrogen sulfate-sulfate anion is a hydrogen-bond acceptor for the three independent cations and the uncoordinated water mol-ecule, the hydrogen-bonding inter-actions giving rise to a three-dimensional hydrogen-bonded network. In the hydrogen sulfate-sulfate species, one of the sulfate groups is disordered in respect of its O atoms in a 2:1 ratio.
在标题盐3C₅H₆NO⁺·HSO₄⁻·SO₄²⁻·H₂O的晶体结构中，硫酸氢根离子通过O—H⋯O氢键与硫酸根离子相连。硫酸氢根 - 硫酸根阴离子是三个独立阳离子和未配位水分子的氢键受体，氢键相互作用形成了三维氢键网络。在硫酸氢根 - 硫酸根物种中，其中一个硫酸根基团的O原子存在2:1比例的无序。
