The crystal structure of the title compound, 2C(3)H(5)N(4)O(2) (+)·SO(4) (2-)·2H(2)O, displays a three-dimensional framework in which mixed infinite chains [oriented parallel to (510) and ([Formula: see text]10)] inter-fere, forming tunnels extending parallel to the c axis. Inter-molecular O-H⋯O, N-H⋯O and O-H⋯N hydrogen bonds ensure the unity of the structure and generate centrosymmetric R(4) (4)(14) and R(4) (2)(8) rings. The S atom lies on a twofold axis.
标题化合物2C₃H₅N₄O₂⁺·SO₄²⁻·2H₂O的晶体结构呈现出三维骨架，其中混合的无限链[平行于(510)和([化学式：见原文]10)取向]相互干扰，形成平行于c轴延伸的隧道。分子间的O-H⋯O、N-H⋯O和O-H⋯N氢键确保了结构的整体性，并生成中心对称的R₄⁴(14)和R₄²(8)环。S原子位于二重轴上。
