Abstract
The title complex crystallizes as a methanol solvate, [Cu2(C16H14O4N2)2(C5H5N)2]·2CH4O. The dinuclear complex is generated from the atoms of the asymmetric unit by inversion symmetry, resulting in a Cu⋯Cu separation of 3.497 (3) A. The copper(II) species has a square-pyramidal geometry, with the basal plane defined by two O atoms and one N atom from the hydrazone ligand and a pyridine N atom. The apical site is occupied by a phenolate O atom in the symmetry-generated hydrazone ligand, which also bonds to the second Cu atom. Intramolecular O—H⋯N hydrogen bonds are formed between the methanol solvent molecules and the uncoordinated N atoms of the hydrazone ligand.
