Abstract: In the title compound, C12H8N2O6, the 1,3-benzodioxole ring system is essentially planar [maximum deviation = 0.036 (2) Å] and the nitro group is oriented at a dihedral angle of 15.4 (1)° with respect to its mean plane. In the crystal, moleucles are linked into C(8)  chains by C-HO hydrogen bonds, and weak aromatic - stacking [centroid-centroid distance = 3.887 (1) Å] also occurs.
