Abstract: The title compound, [Cu2(C13H10NO2)4(CH4O)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 molecule. Each carboxylate 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 intramolecular N-HO hydrogen bonds, and the H atom of the methanol molecule is involved in weak bifurcated hydrogen-bonding interactions with two carboxylate O atoms of related molecules, forming a chain developing parallel to the a axis.
