Abstract: In the title controsymmetric dimeric copper(II) compound, [Cu₂(C₁₀H₇NO₄)₂(H₂O)₂], the Cu^II ion is five-coordinated in a square-pyramidal configuration, with one imine N atom, one phenolate O atom, one carboxylate O atom of the Schiff base and one O atom of a coordinated water molecule defining the basal plane, and the phenolate O atom of another Schiff base occupying the apical position. The Cu^II atoms are bridged by two phenolic O atoms, with a CuCu distance of 3.250 (4) Å. In the crystal structure, the molecules are linked through intermolecular O-HO hydrogen bonds, forming chains running along the b axis.
