In the title compound, [Cd(C4H5NO4)(H2O)2]n, the CdII atom exhibits a distorted octahedral coordination geometry, defined by one N atom and three O atoms from two iminodiacetate (IDA) ligands and two water molecules. The tridentate IDA ligand additionally bridges via one of its carboxylate O atoms to another CdII atom, thus forming a zigzag chain along . A three-dimensional network is completed by intermolecular O-HO and N-HO hydrogen bonds.
