dc.description.abstractThe carb-oxy-lic acid mol-ecule of the title compound, C 11H 20NO 5P·0.25CH 2Cl 2, exists as a zwitterion with the H atom of the phospho-nate group being transferred to the imine N atom. In the asymmetric unit, there are two crystallographically independent acid molecules adopting the same absolute configuration and differing slightly in their geometrical parameters. In each mol-ecule, the imino and carboxyl groups are connected via an intra-molecular N - H⋯O hydrogen bond. Inter-molecular O - H⋯O and N - H⋯O hydrogen bonds induce the formation of layers parallel to the ab plane. The dichloro-methane solvent mol-ecule, with a site occupancy of 0.5, is located between the layers.
