In the title compound, Cu(C(7)H(3)NO(4))(C(5)H(5)N), the Cu(II) atom is in a slightly distorted octa-hedral coordination environment. Each Cu(II) atom is bound to two N atoms and one O atom of the pyridine-dicarboxyl-ate (PDA) ligand in a tridentate manner, one N atom of the pyridine mol-ecule and two bridging carboxyl-ate O atoms of adjacent PDA ligands, leading to a linear one-dimensional chain running along the c axis. These chains are further assembled via weak C-H⋯O and π-π inter-actions into a three-dimensional supra-molecular network structure. The centroid-centroid distance between the π-π inter-acting pyridine rings is 3.9104 (13) Å. The two N atoms are trans to each other with respect to Cu.
在标题化合物[Cu(C₇H₃NO₄)(C₅H₅N)]ₙ中，Cu(II)原子处于略微扭曲的八面体配位环境中。每个Cu(II)原子以三齿方式与吡啶 - 二羧酸酯（PDA）配体的两个N原子和一个O原子、吡啶分子的一个N原子以及相邻PDA配体的两个桥连羧酸酯O原子相连，形成沿c轴延伸的线性一维链。这些链通过弱C - H⋯O和π - π相互作用进一步组装成三维超分子网络结构。π - π相互作用的吡啶环之间的质心 - 质心距离为3.9104 (13) Å。两个N原子相对于Cu彼此呈反式。
