ABSTRACT

In the title biphenyl derivative, C12H9N3O4, the dihedral angle between the benzene rings is 52.84 (10)°. The nitro group attached to the benzene ring is inclined to the ring by 4.03 (2)°, while the nitro group attached to the amino-substituted benzene ring is inclined to the ring by 8.84 (2)°. In the crystal, mol­ecules are linked by two pairs of N—H⋯O hydrogen bonds, forming chains propagating along [101]. Within the chains, these N—H⋯O hydrogen bonds result in the formation of R22(20) and R22(14) ring motifs. The latter ring motif is reinforced by a pair of C—H⋯O hydrogen bonds, enclosing R21(6) ring motifs. The chains are linked by a second C—H⋯O hydrogen bond, forming a three-dimensional supra­molecular structure.

Mentions: In the crystal, mol­ecules are linked by two pairs of N—H⋯O hydrogen bonds, forming chains propagating along the [101] direction. Within the chains, these N—H⋯O hydrogen bonds result in the formation of (20) and (14) ring motifs (Table 1 ▸ and Fig. 2 ▸). The latter ring motif is reinforced by a pair of C—H⋯O hydrogen bonds, enclosing (6) ring motifs (Table 1 ▸ and Fig. 2 ▸). The chains are linked by a second C—H⋯O hydrogen bond (Table 1 ▸), forming a three-dimensional supra­molecular structure, as illustrated in Figs. 3 ▸ and 4 ▸.
