Abstract: The title compound, C₇H₈NO₂⁺·H₂PO₄^-·H₂O, is an ionic compound consisting of dihydrogenmonophosphate anions, water molecules and p-carboxyphenylammonium cations. The asymmetric unit contains two independent entities, i.e. 2(HOOC-C₆H₄-NH₃⁺·H₂PO₄^-·H₂O). Anions and cations are linked to each other through strong hydrogen bonds, formed by all H atoms covalently bonded to anions, nitrogen, carboxylic groups and water molecules. A three-dimensional complex network of hydrogen bonds ensures the cohesion of the ionic structure.
