In the crystal structure of the title compound, C(7)H(6)N(3)O(2) (+)·H(2)PO(4) (-)·C(7)H(5)N(3)O(2)·2H(2)O, the components are connected through O-H⋯O, N-H⋯O and O-H⋯N hydrogen-bonding inter-actions, forming a sheet-like structure parallel to (101). Adjacent sheets are further linked together by strong O-H⋯O hydrogen-bonds involving the dihydrogenphosphate groups. π-π stacking inter-actions between neighbouring aromatic constituents [centroid-centroid distance 3.653 (3) Å] help to consolidate the crystal packing.
在标题化合物C₇H₆N₃O₂⁺·H₂PO₄⁻·C₇H₅N₃O₂·2H₂O的晶体结构中，各组分通过O—H⋯O、N—H⋯O和O—H⋯N氢键相互作用连接在一起，形成了平行于(101)的层状结构。相邻的层通过涉及磷酸二氢根基团的强O—H⋯O氢键进一步连接在一起。相邻芳香成分之间的π-π堆积相互作用[质心-质心距离3.653 (3) Å]有助于巩固晶体堆积。
