X.-Y. Yi, Y.-Z. Li and L.-M. Zheng

Abstract: The title compound, C₆H₈O₄NP·H₂O, contains one phosphonate group and one pyridyl ring connected by a CH(OH) group. The pyridyl N atom and one of the three phosphonate O atoms are protonated. Extensive hydrogen-bonding interactions, as well as --stacking interactions, are found between the molecules, thus generating a three-dimensional supramolecular network structure.
