The title compound, C10H16NO4P.
H2O, contains a zwitterion with a negative charge on the unsubstituted phosphonate O atoms and a positive charge on the N atom of the pyridine ring. The distances between the P and the two unsubstituted phosphonate O atoms [1.503 (2) and 1.483 (2) Å] lie between P-O single- and double-bond distances. The bond angle at the P atom between these O atoms [116.4 (1)°] is larger than the other O-P-O angles. Hydrogen bonds link the unsubstituted phosphonate O atoms through water molecules to the pyridyl N atoms of neighbouring molecules. The presence of the H atom on the N atom of the pyridine ring is associated with a large C-N-C bond angle [124.6 (2)°].
