Abstract
The molecular and crystal structures of three salts of the same anion, N-(2-hydroxyethyl)piperidinium 2-(2,6-dichlorophenylamino)phenylacetate, C 7 H 16 NO + .C 14 H 10 Cl 2 NO 2 - , N-(2-hydroxyethyl)morpholinium 2-(2,6-dichlorophenylamino)phenylacetate, C 6 H 14 NO 2 + .C 14 H 10 Cl 2 NO 2 - , N-(2-hydroxyethyl)piperazinium 2-(2,6-dichlorophenylamino)phenylacetate, C 6 H 15 N 2 O + .C 14 H 10 Cl 2 NO 2 - , have been determined by X-ray diffraction. Strong anion-cation interactions via hydrogen bonds are the prime driving force for crystal self-assembly. Packing is determined by weak hydrogen-bonding interactions (C-H...O and C-H...Cl). The three compounds are isomorphous and are characterized by the same network of hydrogen bonds. Structural results are related to the different solubilities of the three salts.
