Abstract

The title compound, C(5)H(15)NO(6)P(2), was obtained by the reaction of penta-nenitrile with PCl(3) followed by the dropwise addition of water. The asymmetric unit contains one mol-ecule, which exists as a zwitterion with a positive charge on the -NH(3) group and a negative charge on one of the phospho-nic O atoms. The crystal structure displays N-H⋯O and O-H⋯O hydrogen bonding, which creates a three-dimensional network.
