The structure of the title compound, C(8)H(6)Cl(3)NO, contains two mol-ecules in the asymmetric unit. In each independent mol-ecule, the conformation of the N-H bond is almost syn to the ortho-chloro substituent and the conformation of the C=O bond is anti to the N-H bond. The mol-ecules in the crystal structure are linked into supra-molecular chains through N-H⋯O hydrogen bonding along the a axis.
标题化合物C(8)H(6)Cl(3)NO的结构在不对称单元中包含两个分子。在每个独立分子中,N-H键的构象几乎与邻位氯取代基呈顺式,C=O键的构象与N-H键呈反式。晶体结构中的分子通过N-H⋯O氢键沿a轴连接成超分子链。
