1-Carboxymethyl-3-methyl-1H-imidazol-3-ium chloride 2-(3-methyl-1H-imidazol-3-ium-1-yl)acetate monohydrate: a crystal stabilized by imidazolium zwitterions

H. Zhang, L. Chang, N. Wang and X. Xuan

Synopsis: Two imidazolium moieties form a homoconjugated cation through a strong and asymmetric O-H...O hydrogen bond. In the crystal packing, chloride anions and water molecules are linked via O-H...Cl hydrogen bonds, forming an infinite one-dimensional chain.

Formula: C6H9N2O2+·Cl-·C6H8N2O2·H2O
