In the title mol-ecule, C(8)H(8)N(2)O(4), the nitro and meth-oxy-carbonyl groups are twisted from the plane of aromatic ring by 5.1 (1) and 6.2 (1)°, respectively. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules related by translation along the b axis into chains. Weak inter-molecular C-H⋯O inter-actions link further these chains into sheets parallel to the bc plane.
在标题分子C₈H₈N₂O₄中，硝基和甲氧基羰基分别相对于芳香环平面扭转5.1（1）°和6.2（1）°。在晶体中，分子间的N - H⋯O氢键将沿b轴平移相关的分子连接成链。弱的分子间C - H⋯O相互作用进一步将这些链连接成平行于bc平面的片层。
