Abstract
In the title compound, NH4+. C4HO4-. 2/3H(2)O, the hydrogen squarate anions and water molecules are arranged to form planes almost parallel to be. The ammonium cations are located between these planes and cross-link them in t he a direction by means of an extensive network of hydrogen bonds. There ar e two symmetry-independent sets of cations and anions. One of the hydrogen squarate anions and one of the ammonium cations are situated on a twofold a xis and the H atoms of these moieties are disordered over the symmetry-rela ted sites.
