Abstract: In the title complex, [Cu(C₁₆H₁₁Br₂NO₄)(C₃H₇NO)]₂, there are two unique molecules in the asymmetric unit. Each Cu^II atom is coordinated by two O atoms and one N atom from the tridentate ligand L^2- [LH₂ = (E)-2-(3,5-dibromo-2-hydroxybenzylideneamino)-2-(4-hydroxyphenyl)acetic acid] and the O atom of a dimethylformamide molecule to give a slightly distorted square-planar geometry. The two unique molecules form a dimer through weak C-HO hydrogen bonds. In the dimer, the CuCu distance is 3.712 (1) Å. In the crystal structure, molecules form a one-dimensional chain through C-HO hydrogen bonds. These are further aggregated into a three-dimensional network by O-HO and C-HO hydrogen bonds.
