Ammonium 2-(2,4-dichlorophenoxy)acetate hemihydrate

Abstract

The title compound, NH4+·C8H7Cl2O6−·0.5H2O, was prepared by the reaction of 2-(2,4-dichlorophenoxy)acetic acid and ammonia in water at 367 K. The molecular structure and packing are stabilized by N—H...O and O—H...O intermolecular hydrogen-bond interactions.
