In the crystal structure of the title compound, C(4)H(6)N(3) (+)·HSO(4) (-), hydrogen sulfate anions self-assemble through O-H⋯O hydrogen bonds, forming chains along the b axis, while the cations form centrosymmetric pairs via N-H⋯N hydrogen bonds. The 2-amino-pyrimidinium pairs are linked to the sulfate anions via N-H⋯O hydrogen bonds, forming a two-dimensional network parallel to (10[Formula: see text]). In addition, weak inter-molecular C-H⋯O contacts generate a three-dimensional network.
在标题化合物C(4)H(6)N(3) (+)·HSO(4) (-)的晶体结构中，硫酸氢根阴离子通过O-H⋯O氢键自组装，沿b轴形成链，而阳离子通过N-H⋯N氢键形成中心对称对。2-氨基嘧啶鎓对通过N-H⋯O氢键与硫酸根阴离子相连，形成平行于(10[化学式：见原文])的二维网络。此外，弱的分子间C-H⋯O接触形成三维网络。
