The title compound, (C 3 H 12 N 2 )[H 2 AsO 4 ] 2 , contains a network of propane‐1,3‐diaminium cations and dihydrogenarsenate anions [mean As—O = 1.682 (2) Å]. The crystal packing involves anion‐to‐anion O—H⋯O hydrogen bonds, resulting in double chains of dihydrogenarsenate tetrahedra. Cation‐to‐anion N—H⋯O hydrogen bonds generate a three‐dimensional overall structure. One C atom occupies a special position with twofold symmetry.
