Abstract: The title compound, [Cu₂(C₂H₃O₂)₄(C₁₃H₁₂N₂O)₂]·2C₂H₅OH, contains a centrosymmetric dinuclear copper(II) unit bridged by four acetate groups with two pyridine amide ligands occupying the axial positions. Each Cu atom is in a square-pyramidal coordination environment, and is displaced from the basal plane of the O atoms by 0.2071 (3) Å towards the pyridine nitrogen. The CuCu separation is 2.6442 (5) Å. The amide groups of the ligands participate in the formation of intermolecular hydrogen bonds. Hydrogen bonds and - interactions between the pyridyl and benzene rings of neighbouring molecules [centroid-to-centroid distance 3.640 (4) Å] generate a two-dimensional supramolecular network.
