In the crystal structure of the title salt, 2C(5)H(6)NO(+)·SO(4) (2-)·H(2)O, one planar (r.m.s. deviation = 0.01 Å) cation is stacked approximately over the other [dihedral angle between planes = 8.6 (1)°]. The pyridinium and hydr-oxy H atoms are hydrogen-bond donor atoms to the O atoms of the sulfate anion; the cations, anions and water mol-ecules are consolidated into a three-dimensional network through O-H⋯O and N-H⋯O hydrogen bonds.
在标题盐2C₅H₆NO⁺·SO₄²⁻·H₂O的晶体结构中，一个平面（均方根偏差 = 0.01 Å）阳离子大致堆叠在另一个阳离子之上[平面之间的二面角 = 8.6 (1)°]。吡啶鎓和羟基H原子是硫酸根阴离子O原子的氢键供体原子；阳离子、阴离子和水分子通过O—H⋯O和N—H⋯O氢键巩固成三维网络。
