The mol-ecule of the title compound, C(3)H(2)ClN(3)O(2), is almost planar; the dihedral angle between the imidazole ring and the nitro group is 1.7 (2)°. In the crystal structure, pairs of inter-molecular C-H⋯O hydrogen bonds link inversion-related mol-ecules into dimers, generating R(2) (2)(10) ring motifs. The dimers are inter-connected into two-dimensional networks parallel to (102) via inter-molecular N-H⋯N hydrogen bonds. Further stabilization is provided by short inter-molecular Cl⋯O inter-actions [3.142 (2) and 3.1475 (19) Å].
标题化合物C(3)H(2)ClN(3)O(2)的分子几乎是平面的；咪唑环与硝基之间的二面角为1.7 (2)°。在晶体结构中，分子间的C-H⋯O氢键对将反转相关的分子连接成二聚体，形成R(2) (2)(10)环模式。二聚体通过分子间的N-H⋯N氢键相互连接成平行于(102)的二维网络。短的分子间Cl⋯O相互作用[3.142 (2)和3.1475 (19) Å]提供了进一步的稳定性。
