The crystal structure of the title compound, 2C(5)H(6)N(3)O(2) (+)·SO(4) (2-)·2H(2)O, displays a variety of N-H⋯O and O-H⋯O hydrogen bonds in which all potential donors and acceptors are involved. In the crystal, cations and anions are inter-connected, forming R(3) (3)(10) and R(2) (2)(8) ring motifs whereas the anions and water mol-ecules form R(2) (3)(10) rings, which develop in chains running along [100]. The resulting three-dimensional network exhibits undulating sheets parallel to (011), marked by the presence of R(6) (6)(26) rings in which six cations are involved.
标题化合物2C₅H₆N₃O₂⁺·SO₄²⁻·2H₂O的晶体结构显示出多种N-H⋯O和O-H⋯O氢键，其中所有潜在的供体和受体都参与其中。在晶体中，阳离子和阴离子相互连接，形成R₃³(10)和R₂²(8)环 motif，而阴离子和水分子形成R₂³(10)环，这些环沿着[100]方向形成链状结构。由此产生的三维网络呈现出平行于(011)的起伏片状结构，其特征是存在包含六个阳离子的R₆⁶(26)环。
