In the title mol-ecular salt, C5H8N3(+)·C3H3O4(-), the cation is essentially planar, with a maximum deviation of 0.005 (1) Å for all non-H atoms. In the anion, an intra-molecular O-H⋯O hydrogen bond generates an S(6) ring. In the crystal, the cations and anions are connected via N-H⋯O hydrogen bonds and a weak C-H⋯O inter-action, forming layers parallel to the ab plane.
在标题分子盐C₅H₈N₃⁺·C₃H₃O₄⁻中，阳离子基本呈平面状，所有非H原子的最大偏差为0.005 (1) Å。在阴离子中，分子内O—H⋯O氢键形成一个S(6)环。在晶体中，阳离子和阴离子通过N—H⋯O氢键和弱C—H⋯O相互作用相连，形成平行于ab平面的层。
