A charge-assisted hydrogen-bonding network involving N-H⋯O and O-H⋯O hydrogen bonds stabilizes the crystal of the title salt, C5H8N3 (+)·H2PO4 (-). The dihydrogen phosphate anions form one-dimensional chains along [100], via O-H⋯O hydrogen bonds. The 2-amino-4-methyl-pyrimidinium cations are linked to these chains by means of two different kinds of N-H⋯O hydrogen bonds. Neighbouring chains are linked via C-H⋯N and C-H⋯O hydrogen bonds forming two-dimensional slab-like networks lying parallel to (01-1).
一个涉及N-H⋯O和O-H⋯O氢键的电荷辅助氢键网络使标题盐C5H8N3(+)·H2PO4(-)的晶体得以稳定。磷酸二氢根阴离子通过O-H⋯O氢键沿[100]方向形成一维链。2-氨基-4-甲基嘧啶鎓阳离子通过两种不同类型的N-H⋯O氢键与这些链相连。相邻的链通过C-H⋯N和C-H⋯O氢键相连，形成平行于(01-1)的二维板状网络。
