چکیده
The title mol-ecule, C(14)H(11)ClN(4)O(4), is in an E configuration and is twisted with the dihedral angle between the two benzene rings being 38.48 (8)°. The ethyl-idenehydrazine plane makes dihedral angles of 6.03 (10) and 44.04 (11)°, respectively, with the dinitro- and chloro-substituted benzene rings. The two nitro groups are essentially coplanar with the bound benzene ring, making dihedral angles of 0.9 (2) and 1.65 (18)°. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked by a weak C-H⋯O inter-action into a chain along the c axis. The chains are further stacked along the b axis by a π-π inter-action with a centroid-centroid distance of 3.6088 (10) Å.
