Abstract: In the crystal structure of the title compound, C₉H₂₂N₂²⁺·2H₂PO₄^-·H₂O, the H₂PO₄^- anions are hydrogen bonded to each other, forming a ribbon parallel to the b axis. The water molecules connect these ribbons via O-HO hydrogen bonds. The organic cations are attached to the dihydrogen phosphate anions and water molecules through N-HO and C-HO hydrogen bonds, forming an infinite three-dimensional network.
