catena‐Poly[[diaqua­pyridine­cadmium(II)]‐μ‐terephthalato]

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—H⋯O hydrogen bonds, which link adjacent polymeric chains into a three‐dimensional supra­molecular network.
