title: catena-Poly[[bis-(3-carb-oxy-5-nitro-benzoato-κO)copper(II)]-μ-1,3-di-4-pyridylpropane-κN:N'].
abstract: In the title compound, [Cu(C(8)H(4)NO(6))(2)(C(13)H(14)N(2))](n), the square-planar coordinated Cu(II) ion lies on an inversion centre and is coordinated by two protonated 5-nitro-isophthalate ligands. The Cu(II) ions are linked into a one-dimensional coordination polymer by tethering 1,3-di-4-pyridylpropane ligands, whose central methyl-ene C atoms are situated on twofold rotation axes. The chains are oriented parallel to the c axis, and stack into a supra-molecular three-dimensional structure through O-H⋯O hydrogen-bonding inter-actions.
