Propane-1,3-diaminium bis(dihydrogenarsenate)

H. S. Wilkinson and W. T. A. Harrison

Abstract: The title compound, (C₃H₁₂N₂)[H₂AsO₄]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-HO hydrogen bonds, resulting in double chains of dihydrogenarsenate tetrahedra. Cation-to-anion N-HO hydrogen bonds generate a three-dimensional overall structure. One C atom occupies a special position with twofold symmetry.
