Bis(2-nitro­phen­yl)methane

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