In the title compound, C(8)H(9)N(+)·H(2)PO(4) (-), both the cation and anion have crystallographically imposed mirror symmetry (all atoms apart from one O atom lie on the mirror plane). In the crystal, anions and cations are linked by O-H⋯O and π-π stacking inter-actions [centroid-centroid distance = 3.4574 (6) Å], forming chains parallel to the b axis. Adjacent chains are further connected by N-H⋯O hydrogen bonds into a two-dimensional network.
在标题化合物C₈H₉N⁺·H₂PO₄⁻中，阳离子和阴离子在晶体学上均具有镜像对称性（除一个O原子外的所有原子都位于镜面上）。在晶体中，阴离子和阳离子通过O—H⋯O和π–π堆积相互作用相连[质心-质心距离 = 3.4574 (6) Å]，形成平行于b轴的链。相邻的链通过N—H⋯O氢键进一步连接成二维网络。
