title: Oxonium ammonio-(cyclo-prop-yl)methyl-enebis(hydrogenphospho-nate) monohydrate.
abstract: The title compound, H(3)O(+)·C(4)H(10)NO(6)P(2) (-)·H(2)O, was obtained from the reaction of cyclo-propane-carbonitrile with PCl(3), followed by dropwise addition of water. The asymmetric unit comprises an oxonium cation, a zwitterionic monoanion containing a positively charged ammonium group and two negatively charged phospho-nic acid residues and a water mol-ecule of crystallization. The hydroxonium cation and water mol-ecule are hydrogen bonded to the anion and further N-H⋯O and O-H⋯O bonds create a three-dimensional network.
