RESUMO
In the title compound, C13H10N2O4, the nitro groups are twisted significantly relative to the benzene rings [dihedral angles = 16.64â (18) and 28.02â (11)°]. The benzene groups are nearly perpendicular to each other [dihedral angle = 87.72â (6)°]. Short inter-molecular Nâ¯O and Câ¯O [2.981â (2) and 3.060â (2)â Å, respectively] contacts suggest possible weak π-inter-actions between nitro groups and between benzene and nitro groups. In addition, there are π-π inter-actions between one benzene group and an inversion-related equivalent [inter-planar separation = 3.494â (2)â Å].
