The asymmetric unit of the title compound, [Cu(C(9)H(9)O(4))(2)(C(12)H(8)N(2))], contains one half-mol-ecule, the complete mol-ecule being generated by a twofold rotation axis. The Cu(II) atom exhibits a six-coordinated distorted octa-hedral geometry with two N atoms from the phenanthroline ligand [Cu-N 2.007 (2) Å] and four O atoms from two 3,4-dimethoxy-benzoate ligands [Cu-O 1.950 (1) and 2.524 (1) Å]. The difference in Cu-O bond distances indicates a strong Jahn-Teller effect. In the crystal, C-H⋯π inter-actions result in chains of mol-ecules along the c axis.
标题化合物[Cu(C₉H₉O₄)₂(C₁₂H₈N₂)]的不对称单元包含半个分子，完整分子由一个二重旋转轴生成。Cu(II)原子呈现出六配位的扭曲八面体几何构型，其中两个N原子来自邻菲罗啉配体[Cu-N 2.007(2) Å]，四个O原子来自两个3,4-二甲氧基苯甲酸酯配体[Cu-O 1.950(1)和2.524(1) Å]。Cu-O键长的差异表明存在强烈的 Jahn-Teller 效应。在晶体中，C-H⋯π相互作用导致分子沿c轴形成链状结构。
