✦ Synopsis

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) A ˚]. The crystal packing involves anion-to-anion O-HÁ Á ÁO hydrogen bonds, resulting in double chains of dihydrogenarsenate tetrahedra. Cation-toanion N-HÁ Á ÁO hydrogen bonds generate a three-dimensional overall structure. One C atom occupies a special position with twofold symmetry.
