The asymmetric unit of the title compound, 2C(6)H(9)N(2) (+)·SO(4) (2-)·H(2)O, contains two isomeric protonated amino-methyl-pyridine cations, a sulfate anion and a solvent water mol-ecule. The cations are in the iminium tautomeric form. In the crystal structure, inter-molecular O-H⋯O, N-H⋯O and weak C-H⋯O hydrogen bonds link the components into a three-dimensional network. Additional stabilization is provided by weak π-π stacking inter-actions, with centroid-centroid distances of 3.758 (2) and 3.774 (1) Å.
标题化合物2C₆H₉N₂⁺·SO₄²⁻·H₂O的不对称单元包含两个异构的质子化氨基甲基吡啶阳离子、一个硫酸根阴离子和一个溶剂水分子。阳离子呈亚胺鎓互变异构形式。在晶体结构中，分子间的O—H⋯O、N—H⋯O和弱C—H⋯O氢键将各组分连接成三维网络。通过弱π-π堆积相互作用提供了额外的稳定性，质心间距为3.758 (2) Å和3.774 (1) Å。
