The structure of the title compound, [Cu(C14H9NO4)(C12H8N2)] n , consists of zigzag polymeric chains along the c axis. The asymmetric unit contains one Cu(II) atom which is coordinated by one 2,2'-imino-dibenzoate ligand and a one phenanthroline unit. Two intra-molecular N-H⋯O hydrogen bonds occur. The supra-molecular structure is characterized by weak C-H⋯O hydrogen bonds and π-π stacking inter-actions, forming a three-dimensional supramolecular network. The shortest centroid-centroid distances between neighbouring phenanthroline aromatic rings and 2,2'-imino-dibenzoate rings are 3.684 (1) and 3.640 Å, respectively. The shortest intra-chain Cu⋯Cu distance is 7.2885 (9) and the shortest Cu⋯Cu distance between Cu atoms in different chains is 7.1103 (6) Å.
标题化合物[Cu(C₁₄H₉NO₄)(C₁₂H₈N₂)]ₙ的结构由沿c轴的锯齿状聚合物链组成。不对称单元包含一个Cu(II)原子，该原子由一个2,2'-亚氨基二苯甲酸酯配体和一个菲咯啉单元配位。存在两个分子内N-H⋯O氢键。超分子结构的特征是存在弱C-H⋯O氢键和π-π堆积相互作用，形成三维超分子网络。相邻菲咯啉芳香环与2,2'-亚氨基二苯甲酸酯环之间最短的质心-质心距离分别为3.684 (1) Å和3.640 Å。链内最短的Cu⋯Cu距离为7.2885 (9) Å，不同链中Cu原子之间最短的Cu⋯Cu距离为7.1103 (6) Å。
