Abstract

The title compound, DL-threonine - arsenic acid (1/1), C4H9NO3 center dot H3AsO4, is an unusual adduct containing zwitterionic threonine and neutral arsenic acid molecules. The component species interact by way of N - H center dot center dot center dot O and O-H center dot center dot center dot O hydrogen bonds, leading to parallel [ 001] chains of threonine and arsenic acid molecules which are crosslinked by further O - H center dot center dot center dot O and N - H center dot center dot center dot O bonds, resulting in a three-dimensional network.
