The title compound, [Cu(2)(C(13)H(10)NO(2))(4)(CH(4)O)(2)], has been prepared by the reaction of 2-anilinobenzoic acid, HL, with copper(II) nitrate in methanol. This dinuclear complex is arranged around an inversion center. Each Cu atom displays a distorted trigonal-pyramidal coordination with four O atoms from the four ligands L and one axial O atom of the methanol solvent mol-ecule. Each carboxyl-ate group of the ligands L links two Cu atoms, building a dinuclear complex with a Cu-Cu distance of 2.5774 (10) Å. There are intra-molecular N-H⋯O hydrogen bonds, and the H atom of the methanol mol-ecule is involved in weak bifurcated hydrogen-bonding inter-actions with two carboxyl-ate O atoms of related mol-ecules, forming a chain developing parallel to the a axis.
标题化合物[Cu₂(C₁₃H₁₀NO₂)₄(CH₄O)₂]是通过2-氨基苯甲酸（HL）与硝酸铜（II）在甲醇中反应制备的。该双核配合物围绕一个倒转中心排列。每个铜原子与来自四个配体L的四个氧原子以及甲醇溶剂分子的一个轴向氧原子形成扭曲的三角锥配位。配体L的每个羧酸根基团连接两个铜原子，形成一个铜-铜距离为2.5774(10) Å的双核配合物。存在分子内N-H⋯O氢键，甲醇分子的氢原子与相关分子的两个羧酸根氧原子参与弱的分叉氢键相互作用，形成平行于a轴延伸的链。
