摘要：
The title compound, C20H12N4O4, contains two benzene rings ortho bonded to a quinoxaline nucleus. The dihedral angle between the benzene rings is 59.2 (4)°. The two benzene rings adopt a trans configuration with respect to the quinoxaline plane. The formal C - C -bond substituted by nitro-phenyl groups is shorter than normal C - C bonds and the C(benzene) - C(quinoxaline) bonds. These features are consistent with electron delocalization over the whole mol-ecule. © International Union of Crystallography 2007.
