Crystal structure of di­bromido­(N,N-di­methyl­formamide-κO){2-(1H-indol-3-yl)-N-[(quinolin-2-yl-κN)methyl­idene]ethanamine-κN}cadmium

In the mononuclear title complex, [CdBr(2)(C(20)H(17)N(3))(C(3)H(7)NO)], synthesized from the quinoline-derived Schiff base 2-(1H-indol-3-yl)-N-(quinolin-2-yl­methyl­ene)ethan­amine (IQME), the coordination geometry around the Cd(2+) 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 Cd(II) 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.
