title: [Bis(quinolin-2-ylcarbon-yl)amido-κ(3) N,N',N'']bromido-(N,N-di-methyl-formamide-κO)copper(II).
abstract: In the mononuclear title complex, [CuBr(C20H12N3O2)(C3H7NO)], synthesized from the quinoline-derived reduced Schiff base 4-(quinolin-2-ylmeth-yl)amino-phenol, the coordination geometry around Cu(2+) 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 di-methyl-formamide O-atom donor [Cu-O = 2.078 (2) Å] and three N-atom donors from the monoanionic, tridentate bis-(quinolin-2-ylcarbon-yl)di-imide ligand [Cu-Ndi-imide = 1.941 (3) Å, and Cu-Nquinol-yl = 2.060 (3) and 2.049 (3) Å]. An intra-molecular C-H⋯O occurs. In the crystal, weak methyl and aromatic C-H⋯Br and formyl C-H⋯Ocarbon-yl hydrogen-bonding inter-actions generate an overall layered structure lying parallel to (001).
