title: Tetra-kis(μ-2-anilinobenzoato)bis-[methano-lcopper(II)](Cu-Cu).
abstract: 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.
