Abstract: The title compound, [Cd(C₈H₄O₄)(C₅H₅N)(H₂O)₂]_n, is a one-dimensional spiral polymer in which the organic species act in bis-monodentate and bis-bidentate coordination modes. The two crystallographically independent terephthalate ligands lie on centers of symmetry. The Cd²⁺ cation is hexacoordinated in a distorted octahedral geometry by five O atoms [Cd-O = 2.2370 (16)-2.4928 (17) Å] and one N atom [Cd-N = 2.316 (2) Å]. The water molecules and carboxylate O atoms are involved in O-HO hydrogen bonds, which link adjacent polymeric chains into a three-dimensional supramolecular network.
