The title molecule, C15H20NO5P, has a zwitterionic structure with strong intermolecular N ... O and O ... O hydrogen bonds. The coordination around phosphorus is distorted tetrahedral, with a maximum bond-angle deviation of 12 degrees from the ideal. The P--C bond length is 1.860 (4) Angstrom and the average P-O value is 1.518 (3) Angstrom.
