Abstract: The title compound, C9H8N2O8, was obtained by the reaction of imidazole-4,5-dicarboxylic acid and 2-chloroacetic acid. An intramolecular O-HO hydrogen bond occurs. The crystal packing is stabilized by intermolecular O-HO and C-HO hydrogen bonds, which link molecules into a three-dimensional network.
