In the cation of the title compound, [Cu(C2H8N2)2(CH3OH)2](C8H4O4)·2CH3OH, the CuII atom lies on an inversion centre. The four N atoms of two ethylenediamine ligands around the CuII atom form the equatorial plane, while two methanol O atoms in the axial positions complete a Jahn–Teller distorted octahedral coordination. The benzene-1,4-dicarboxylate anion is centrosymmetric. In the crystal, C—HO, N—HO and O—HO hydrogen bonds link the cations, the anions and the methanol solvent molecules.
