catena-Poly[[aqua­bis­(pyridine-κN)copper(II)]-μ-2,2′-(p-phenyl­enedi­oxy)diacetato-κ(2) O:O′]

In the title compound, [Cu(C(10)H(8)O(6))(C(5)H(5)N)(2)(H(2)O)](n), the Cu atom is five-coordinated by two O atoms from two carboxyl­ate groups of two different 2,2′-(p-phenyl­enedi­oxy)diacetate ligands, two N atoms from two pyridine mol­ecules and one water O atom. The geometry is square-pyramidal with the water O atom occupying the apical position. The carboxyl­ate group bridges adjacent Cu atoms, forming an infinite zigzag chain extending parallel to [001]. The chains are linked into layers by O—H⋯O hydrogen bonds. The Cu and water O atoms lie on special positions of site symmetry 2.
