In the title complex, [Cu(C(16)H(11)Br(2)NO(4))(C(3)H(7)NO)](2), there are two unique mol-ecules in the asymmetric unit. Each Cu(II) atom is coordinated by two O atoms and one N atom from the tridentate ligand L(2-) [LH(2) = (E)-2-(3,5-dibromo-2-hydroxy-benzyl-idene-amino)-2-(4-hydroxy-phenyl)acetic acid] and the O atom of a dimethyl-formamide mol-ecule to give a slightly distorted square-planar geometry. The two unique mol-ecules form a dimer through weak C-H⋯O hydrogen bonds. In the dimer, the Cu⋯Cu distance is 3.712 (1) Å. In the crystal structure, mol-ecules form a one-dimensional chain through C-H⋯O hydrogen bonds. These are further aggregated into a three-dimensional network by O-H⋯O and C-H⋯O hydrogen bonds.
