Abstract: The title compound, [Cu₂(C₁₅H₁₁BrN₂O₄)₂(C₃H₇NO)₂], is derived from the reaction of N'-(5-bromo-2-hydroxy-3-methoxybenzylidene)-2-hydroxybenzohydrazide and copper nitrate in a dimethylformamide solution in the presence of sodium hydroxide. The compound can be regarded as a binuclear centrosymmetric complex. In the crystal, the Cu^II atom is fivefold surrounded and adopts a distorted square-pyramidal coordination environment. An intramolecular O-HN hydrogen bond stabilizes the molecular conformation.
