In the title compound, C25H20N2O5S, the benzodioxole ring system is essentially planar [maximum deviation = 0.021 (2) Å] and forms dihedral angles of 85.2 (1) and 74.2 (1)°, respectively, with the formyl benzene and sulfonyl-bound benzene rings. In the crystal, C—HO hydrogen bonds generate C(8) chains along [100] and R33(19) ring motifs. In addition, a weak π–π interaction [centroid–centroid distance = 3.937 (3) Å] is also observed.

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) [101] chains by C—HO hydrogen bonds, and weak aromatic π–π stacking [centroid–centroid distance = 3.887 (1) Å] also occurs.
