In the mononuclear title complex, [CdBr2(C20H17N3)(C3H7NO)], synthesized from the quinoline-derived Schiff base 2-(1H-indol-3-yl)-N-(quinolin-2-ylmethylene)ethanamine (IQME), the coordination geometry around the Cd2+ atom is distorted trigonal bipyramidal, the axial positions being occupied by the quinoline N atom [Cd—N = 2.401 (3) Å] and one dimethylformamide O-atom donor [Cd—O = 2.399 (2) Å]. The equatorial plane is formed by the imine N atom [Cd—N = 2.293 (3) Å] and two bromides [Cd—Br = 2.5621 (8) and 2.5676 (8) Å], with the deviation of the CdII atom from the equatorial plane being 0.046 (1) Å. An intramolecular C—H...Br interaction occurs. In the crystal, N—H...Br interactions generate [101] chains.
