In the title compound, [Cu(C10H8O6)(C5H5N)2(H2O)]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 . The chains are linked into layers by O-HO hydrogen bonds. The Cu and water O atoms lie on special positions of site symmetry 2.
