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).
在由喹啉衍生的还原席夫碱4-(喹啉-2-基甲基)氨基苯酚合成的单核标题配合物[CuBr(C₂₀H₁₂N₃O₂)(C₃H₇NO)]中,Cu(Ⅱ)周围的配位几何形状为扭曲的四方锥,锥顶为溴阴离子[Cu-Br = 2.4671 (5) Å]。锥底由一个二甲基甲酰胺O原子供体[Cu-O = 2.078 (2) Å]和来自单阴离子三齿双(喹啉-2-基羰基)二亚胺配体的三个N原子供体构成[Cu-N二亚胺 = 1.941 (3) Å,Cu-N喹啉基 = 2.060 (3)和2.049 (3) Å]。存在分子内C-H⋯O相互作用。在晶体中,弱的甲基和芳香族C-H⋯Br以及甲酰基C-H⋯O羰基氢键相互作用产生了平行于(001)的整体层状结构。
