title: [Amino-(iminio)meth-yl]phospho-nate.
abstract: The title compound, CH(5)N(2)O(3)P, exists as a zwitterion. The N atom of the imino group is protonated and the phospho-nic acid group is deprotonated. The mol-ecular geometry about the central C atom of this zwitterionic species was found to be strictly planar with the sum of the three angles about C being precisely 360°. In the crystal, the mol-ecules are inter-linked by O-H⋯O and N-H⋯O hydrogen-bonding inter-actions, forming a three-dimensional supra-molecular network structure.
