Abstract
The structure of the salt of 2-(2,6-dichlorophenylamino)phenylacetic a cid (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 hydr ogen bonds between the ammonium H atom and the phenylacetate group; th is may be attributed to the presence of a weak trifurcated intramolecu lar N-H ...(O)(3) hydrogen bond within the cation. Inter-ion hydrogen bonds are established through the OH groups of the cations leading to a two-dimensional network.
