The asymmetric unit of the title compound, C(8)H(12)N(+)·H(2)PO(4) (-), contains two H(2)PO(4) (-) anions and two 2,4,6-trimethyl-pyridinium cations. In the crystal, the anions are linked by O-H⋯O hydrogen bonds, forming supra-molecular chains running along the a axis; the cations are connected to the anion chains by N-H⋯O hydrogen bonds. Weak inter-molecular C-H⋯O hydrogen bonding is also present in the crystal structure.
标题化合物C(8)H(12)N(+)·H(2)PO(4) (-)的不对称单元包含两个H(2)PO(4) (-)阴离子和两个2,4,6-三甲基吡啶阳离子。在晶体中，阴离子通过O-H⋯O氢键相连，形成沿a轴延伸的超分子链；阳离子通过N-H⋯O氢键与阴离子链相连。晶体结构中还存在弱的分子间C-H⋯O氢键。
