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