Abstract

The title compound, NH(4) (+)·C(5)H(14)NO(6)P(2) (-), was obtained from 1-ammonio-1-phosphono-pentane-1-phospho-nic acid and ammonium hydroxide in aqueous solution. The asymmetric unit of title compound contains one molecule, which consists of an ammonium cation and an aminodiphosphonic anion with the H atoms transferred from the phosphonic acid group to the amino group. The crystal structure shows a three-dimensional network of O-H⋯O and N-H⋯O hydrogen bonds which stabilize the structure.
