In the title complex, [Cd2(C9H6O5)2(C7H6N2)4(H2O)2]·2H2O, the CdII atoms are linked by two 3-carboxy­phenoxy­acetate groups into a centrosymmetric dimer. Each CdII atom displays a distorted octa­hedral coordination geometry, with three carboxylate O atoms from different 3-carboxy­phenoxy­acetate groups, two N atoms from two benzimidazole co-ligands and one water mol­ecule. Inter­molecular hydrogen bonding leads to a two-dimensional supramolecular network.
