Özet

In the title biphenyl derivative, C12H9N3O4, the dihedral angle between the benzene rings is 52.84 (10)degrees. The nitro group attached to the benzene ring is inclined to the ring by 4.03 (2)degrees, while the nitro group attached to the aminosubstituted benzene ring is inclined to the ring by 8.84 (2)degrees. In the crystal, molecules are linked by two pairs of N-H center dot center dot center dot O hydrogen bonds, forming chains propagating along [101]. Within the chains, these N-H center dot center dot center dot O hydrogen bonds result in the formation of R-2(2)(20) and R-2(2)(14) ring motifs. The latter ring motif is reinforced by a pair of C-H center dot center dot center dot O hydrogen bonds, enclosing R-2(1)(6) ring motifs. The chains are linked by a second C-H center dot center dot center dot O hydrogen bond, forming a threedimensional supramolecular structure.
