(E)-1-(2,4-Dinitro-phen-yl)-2-[1-(2-meth-oxy-phen-yl)ethyl-idene]hydrazine.

The mol-ecule of the title compound, C(15)H(14)N(4)O(5), is in an E conformation with respect to the C=N double bond and the dihedral angle between the two benzene rings is 37.83 (7)°. The ethyl-idenehydrazine plane makes dihedral angles of 4.93 (9) and 42.38 (9)° with the two benzene rings. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked by weak C-H⋯O inter-actions into chains along the c axis which are stacked along the b axis by aromatic π-π inter-actions with a centroid-centroid distance of 3.5927 (10) Å.
