Abstract: In the title complex, [Cu₂(C₁₁H₁₁N₃O₂)₂(C₅H₅N)₂]·CH₄O, the two Cu^II atoms are bridged by two oxime O atoms of diacetyl monoxime benzoylhydrazone ligands, with a CuCu distance of 3.644  (2)  Å. The center of the dimer corresponds to a crystallographic center of symmetry. Each Cu^II atom shows a square-pyramidal geometry defined by two N and two O atoms of hydrazone ligands and one pyridine N atom. The methanol solvent molecules lie on special positions with twofold rotation symmetry and form intramolecular O-HO hydrogen bonds.
