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.
标题分子C(14)H(11)ClN(4)O(4)呈E构型，两个苯环之间的二面角为38.48 (8)°，呈扭曲状。亚乙基肼平面与二硝基和氯取代的苯环分别形成6.03 (10)°和44.04 (11)°的二面角。两个硝基与相连的苯环基本共面，二面角分别为0.9 (2)°和1.65 (18)°。分子内的N-H⋯O氢键形成一个S(6)环 motif。在晶体中，分子通过弱的C-H⋯O相互作用沿c轴连接成链。这些链通过π-π相互作用沿b轴进一步堆积，质心-质心距离为3.6088 (10) Å。
