The title polymeric compound, {[Cd(2)(C(7)H(3)NO(5))(2)(H(2)O)(4)]·4H(2)O}(n) or {[Cd(2)(hypydc)(2)(H(2)O)(4)]·4H(2)O}(n) (where hypydcH(2) is 4-hydroxy-pyridine-2,6-dicarboxylic acid), was synthesized by the reaction of cadmium(II) nitrate hexa-hydrate with 4-hydroxy-pyridine-2,6-dicarboxylic acid and propane-1,3-diamine, in a 1:2:2 molar ratio in aqueous solution. The compound is a seven-coordinate binuclear polymeric complex with distorted penta-gonal bipyramidal geometry around Cd(II) [Cd-O = 2.247 (4)-2.474 (3) Å]. In the binuclear monomeric units, the central atoms join together by O atoms of two bridging tridentate (hypydc)(2-) ligands, and the polymer propagates via two bridging water mol-ecules that link each Cd(II )centre of one monomer to the adjacent neighbour. Propane-1,3-diamine (pn) does not appear in the product but plays a role as a base. Inter-molecular O-H⋯O and C-H⋯O hydrogen bonds, and π-π stacking inter-actions, with distances of 3.725 (3) and 3.766 (3) Å, connect the various components.
