Crystal structures and packing motifs of 2,3-diphenylquinoxaline and 2,3-diphenylbenzo[g]quinoxaline

2,3-Bis(3-nitrophenyl)quinoxaline

“…The structure of a related molecule, 2,3-diphenylquinoxaline, has been reported previously (Cantalupo et al, 2006;Rajnikant et al, 2006).…”

“…For related literature, see: Cantalupo et al (2006); He et al (2003); Lindsley et al (2005); Loriga et al (1997); Rajnikant et al (2006); Seitz et al (2002). Selected geometric parameters (Å , ).…”

2-(2-Chlorophenyl)-3-(3,4-dimethoxyphenyl)quinoxaline

“…The quinoxaline moiety yields a wide variety of potential bidentate bridges in polymeric networks with silver, see: Patra et al (2007). For the synthesis and characterization of quinoxalines, see: Crundwell & Stacy (2005), of benzo[g]quinoxalines, see: Cantalupo et al (2006) and of pyrazino[2,3-g]quinoxalines, see: Bellizzi et al (2006).…”

“…The Crundwell lab has synthesized and characterized many quinoxalines (Crundwell et al, 2005), benzo[g]quinoxalines (Cantalupo et al, 2006), and pyrazino[2,3-g]quinoxalines (Bellizzi et al, 2006) as potential metal ligands. The title compound was formed by the condensation of two commercial products: 1,2-phenylenediamine and 2-chloro-3′,4′-dimethoxybenzil.…”

2,3,7,8-Tetrakis(5-chlorothien-2-yl)pyrazino[2,3-g]quinoxaline–para-xylene (3/2)

“…Reactions of diamines and diketones lead to the easy formation of nitrogen-containing heterocyclic species such as quinoxalines (Stacy & Crundwell, 2005), benzo [g]quinoxalines (Cantalupo et al, 2006) and pyrazinoquinoxalines. Part of our ongoing research is to find nitrogen-containing heterocycles that may bind metals or that may have novel electronic properties.…”
