[Bis(quinolin-2-ylcarbonyl)amido-κ³N,N′,N′′]bromido(N,N-dimethylformamide-κO)copper(II)

Abstract

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).

Crystal structure of 2-amino-1,3-dibromo-6-oxo-5,6-dihydropyrido[1,2-a]quinoxalin-11-ium bromide monohydrate

“…There are very few examples of similar compounds in the literature, a search of the Cambridge Structural Database (Version 5.35, May 2014; Groom & Allen, 2014) revealing the structure of 2-azaniumyl-3-bromo-6-oxo-5,6-dihydropyrido-[1,2-a]quinoxalin-11-ium dibromide (Faizi et al, 2015), in which the 2-amino-1,2-dibromide ring in the title compound is replaced by a 2-azaniumyl-3-bromo ring. Other similar structures have been reported (Faizi & Sen, 2014;Koner et al, 2008).…”

“…These compounds have also found applications as dyes (Zaragoza et al, 1999;Sonawane & Rangnekar, 2002) and building blocks in the synthesis of organic semiconductors (Katoh et al, 2000;Dailey et al, 2001) and they also serve as useful rigid subunits in macrocyclic receptors for molecular recognition (Mizuno et al, 2002) and chemically controllable switches (Elwahy, 2000). The present work is a part of an ongoing structural study of Schiff bases and their utilization in the synthesis of new organic and polynuclear coordination compounds (Faizi & Sen, 2014;Moroz et al, 2012). We report here the synthesis and crystal structure of 2-amino-1,3-dibromo-6-oxo-5,6-dihydropyrido[1,2-a]quinoxalin-11-ium bromide monohydrate (refcode ADOQBM).…”
