Poly[diaqua­(μ-4,4′-bipyridine-κ(2) N:N′)[μ-2,2′-(p-phenyl­enedi­oxy)diacetato-κ(2) O:O′]cadmium]

In the title compound, [Cd(C(10)H(8)O(6))(C(10)H(8)N(2))(H(2)O)(2)](n), the Cd(II) ion has inversion symmetry and is coordinated by O atoms from two water mol­ecules and two bridging 2,2′-(μ-p-phenyl­enedi­oxy)diacetate ligands and two N atoms from two 4,4′-bipyridine ligands, giving a slightly distorted octa­hedral geometry. The diacetate and 4,4′-bipyridine ligands also lie across inversion centers. The bridging ligands form layers parallel to (11[Image: see text]), with adjacent layers inter­connected via O—H⋯O hydrogen bonds between the coordinated water mol­ecules and the carboxyl­ate O atoms, giving a three-dimensional supra­molecular architecture.
