✦ Synopsis
In the title compound, C~4~H~12~N~2~
^2+^·HAsO~4~
^2−^·H~2~O, the component species interact by way of N—H...O and O—H...O hydrogen bonds, the latter leading to infinite sheets of HAsO~4~
^2−^ anions and water molecules containing R

The title compound, (C 3 H 12 N 2 )[HAsO 4 ]ÁH 2 O, contains a network of propane-1,3-diaminium cations, hydrogenarsenate anions [mean As-O = 1.687 (2) A ˚] and water molecules. The crystal packing involves anion-to-anion and water-to-anion O-HÁ Á ÁO hydrogen bonds, resulting in infinite chains cont
The asymmetric unit of the title compound, C 4 H ÁH 2 O, contains one water molecule, one anion and two half-cations, both cations having chair conformations. The crystal structure is stabilized by intra-and intermolecular O-HÁ Á ÁO and N-HÁ Á ÁO hydrogen bonds, linking the molecules into a three-d
