There are two mol-ecules in the asymmetric unit of the title compound, C(8)H(4)ClNO(2). In the crystal, they are linked by N-H⋯O hydrogen bonds, generating centrosymmetric, tetra-meric assemblies. A C-H⋯O inter-action also occurs.
标题化合物C₈H₄ClNO₂的不对称单元中有两个分子。在晶体中,它们通过N-H⋯O氢键相连,形成中心对称的四聚体聚集体。还存在C-H⋯O相互作用。
