1-(2-Carboxyethyl)-3-(carboxylatomethyl)-2-ethylbenzimidazol-1-ium monohydrate
Abstract
In the title compound, C14H16N2O4·H2O, three substituent groups are located on the same side of the benzimidazole ring plane. In the crystal, O—H...O hydrogen bonds and π–π stacking between parallel imidazole rings [centroid–centroid distance = 3.858 (4) Å] link the molecules into a three-dimensional supramolecular structure.
