Abstract: In the title compound, [Cd(C₇H₇N₂O₄)₂]_n, C₇H₇N₂O₄^- zwitterions link Cd²⁺ cations into a network of [Cd(C₇H₇N₂O₄)₂]_n sheets. The carboxylate arms of the ligand chelate to the metal, which shows square-antiprismatic coordination. The Cd²⁺ ion occupies a special position 2 site symmetry. The crystals were found to be twinned.
