Summary:The title compound, NH4+·C2H8NO6P2−·2H2O, was obtained by the reaction between 1-aminoethane-1,1-diyldiphosphonic acid and ammonium hydroxide (1:1) in an aqueous solution. The asymmetric unit contains one anion with two H atoms transferred from the phosphonic acid groups to the amino group of the anion and to an ammonia molecule, giving an ammonium cation. The structure displays N-H...O and O-H...O hydrogen bonding, which creates a three-dimensional network.
