The title compound, C(13)H(16)N(4)O(4), is a new hydrazone. An intra-molecular N-H⋯O hydrogen bond generates a six-membered ring, producing an S(6) ring motif. The nitro groups in the ortho and para positions are almost coplanar with the benzene ring to which they are bound, making dihedral angles of 0.60 (11) and 3.18 (11)°, respectively. Pairs of inter-molecular C-H⋯O hydrogen bonds link neighbouring mol-ecules into inversion dimers with R(2) (2)(10) motifs. The crystal structure is further stabilized by inter-molecular π-π inter-actions, with a benzene centroid-to-centroid distance of 3.6601 (4) Å.
标题化合物C(13)H(16)N(4)O(4)是一种新型腙。分子内N-H⋯O氢键形成一个六元环，产生S(6)环模式。邻位和对位的硝基与它们所连接的苯环几乎共面，二面角分别为0.60 (11)°和3.18 (11)°。分子间的C-H⋯O氢键对将相邻分子连接成具有R(2) (2)(10)模式的反演二聚体。晶体结构通过分子间的π-π相互作用进一步稳定，苯环质心到质心的距离为3.6601 (4) Å。
