| Summary: | In the mononuclear title complex, [CuBr(C20H12N3O2)(C3H7NO)], synthesized from the quinoline-derived reduced Schiff base 4-(quinolin-2-ylmethyl)aminophenol, the coordination geometry around Cu2+ is distorted square-pyramidal, comprising a bromide anion at the apex [Cu—Br = 2.4671 (5) Å]. The base of the pyramid is built up from one dimethylformamide O-atom donor [Cu—O = 2.078 (2) Å] and three N-atom donors from the monoanionic, tridentate bis(quinolin-2-ylcarbonyl)diimide ligand [Cu—Ndiimide = 1.941 (3) Å, and Cu—Nquinolyl = 2.060 (3) and 2.049 (3) Å]. An intramolecular C—H...O occurs. In the crystal, weak methyl and aromatic C—H...Br and formyl C—H...Ocarbonyl hydrogen-bonding interactions generate an overall layered structure lying parallel to (001).
