The structure of the salt of 2-(2,6-dichlorophenylamino)phenylacetic acid (HD) with tris(2-hydroxyethyl)amine (TEA), C6H16NO3+.C14H10Cl2NO2−, consists of hydrogen-bonded HTEA+ cations and D− anions, as found in similar acid–base adducts of HTEA. There are no intermolecular hydrogen bonds between the ammonium H atom and the phenylacetate group, which may be attributed to the presence of a weak trifurcated intramolecular N—H(O)3 hydrogen bond within the cation. Interion hydrogen bonds are established through the OH groups of the cations, leading to a two-dimensional network.
