In the title compound, Cu(2)(C(7)H(3)ClNO(4))(4), 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.
在标题化合物[Cu₂(C₇H₃ClNO₄)₄]ₙ中，每个Cu(II)离子周围的配位几何构型为扭曲的四方锥。CuO₅配位由来自五个5-氯-2-硝基苯甲酸酯配体的羧酸根基团的五个O原子形成。这种配位导致形成中心对称的双核单元，这些单元通过边缘共享沿着a轴形成线性链，Cu(II)离子交替间隔2.5891 (4) 和3.1763 (4) Å。这些链通过C—H⋯O相互作用相互连接成三维网络。
