title: catena-Poly[[bis-(5-chloro-2-nitro-benzoato)copper(II)]-bis-(μ-5-chloro-2-nitro-benzoato)].
abstract: In the title compound, [Cu(2)(C(7)H(3)ClNO(4))(4)](n), the coordination geometry around each Cu(II) ion is distorted square-pyramidal. The CuO(5) coordination is formed by five O atoms from the carboxyl-ate groups of five 5-chloro-2-nitro-benzoate ligands. This coordination leads to the formation of centrosymmetric binuclear units which are edge-shared, forming a linear chain along the a axis, with the Cu(II) ions alternately separated by 2.5891 (4) and 3.1763 (4) Å. The chains are inter-connected into a three-dimensional network by C-H⋯O inter-actions.
