چکیده
The title compound, NH(4) (+)·C(2)H(8)NO(6)P(2) (-)·2H(2)O, was obtained by the reaction between 1-amino-ethane-1,1-diyldiphospho-nic acid and ammonium hydroxide (1:1) in an aqueous solution. The asymmetric unit contains one anion with two H atoms transferred from the phospho-nic acid groups to the amino group of the anion and to an ammonia mol-ecule, giving an ammonium cation. The structure displays N-H⋯O and O-H⋯O hydrogen bonding, which creates a three-dimensional network.

The title complex, H(3)O(+)·NH(3)C(CH(3))(PO(3)H)(2) (-), contains a hydroxonium ion and an NH(3)C(CH(3))(PO(3)H)(2) (-) anion. The three H atoms of H(3)O(+) form a pseudo-tetra-hedron by being distributed over four positions with occupation factors of 0.75. Multiple N-H⋯O and O-H⋯O hydrogen bonds in the crystal structure form an intricate three-dimensional supra-molecular network.
