Abstract

In the title compound, C14H14N4O4, the dihedral angle between the benzene rings is 10.42 (8)°. The nitro groups make dihedral angles of 5.3 (2) and 6.47 (15)° with their parent ring and are oriented at 11.2 (3)° with respect to each other. An intramolecular N—H⋯O hydrogen bond completes an S(6) ring motif. In the crystal, molecules are linked by C—H⋯O interactions, thus forming (010) chains in which R 2 2(13) ring motifs are present. There also exist aromatic π–π stacking interactions [centroid–centroid separation = 3.7046 (9) Å].

Highlights

In the title compound, C14H14N4O4, the dihedral angle between the benzene rings is 10.42 (8)
There exist an intramolecular H-bonding of N—H···O type completing an S(6) (Fig. 2) ring motif (Bernstein et al, 1995)
The molecules are stabilized in the form of infinite one dimensional polymeric chains due to C—H···O type of intermolecular H-bondings (Table 1, Fig. 2) extending along the b axis and in these chains R22(13) ring motifs are present
