Abstract: In the title compound, [Cu₂(C₇H₃ClNO₄)₄]_n, the coordination geometry around each Cu^II ion is distorted square-pyramidal. The CuO₅ coordination is formed by five O atoms from the carboxylate groups of five 5-chloro-2-nitrobenzoate 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 interconnected into a three-dimensional network by C-HO interactions.
