Abstract
In the title complex, [Cu(C16H11Br2NO4)(C3H7NO)]2, there are two unique molecules in the asymmetric unit. Each CuII 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—H⋯O hydrogen bonds. In the dimer, the Cu⋯Cu distance is 3.712 (1) Å. In the crystal structure, molecules 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.
