In the structure of the title compound (N26DCP2CBA), C(13)H(8)Cl(3)NO, the conformations of N-H and C=O bonds in the amide group are trans to each other, similar to that observed in N-(2,6-dichloro-phen-yl)benzamide, 2-chloro-N-phenyl-benzamide, 2-chloro-N-(2-chloro-phen-yl)benzamide and 2-chloro-N-(2,3-dichloro-phen-yl)benzamide with similar bond parameters. Furthermore, the position of the amide O atom is syn to the ortho-chloro group in the benzoyl ring. The amide group makes a dihedral angle of 59.8 (1)° with the benzoyl ring, while the benzoyl and aniline rings make a dihedral angle of 8.1 (2)°. The mol-ecules are linked by N-H⋯O hydrogen bonds into infinite chains running along the b axis.
在标题化合物（N26DCP2CBA）C(13)H(8)Cl(3)NO的结构中，酰胺基团中N - H键和C = O键的构象相互呈反式，类似于在N-(2,6 - 二氯苯基)苯甲酰胺、2 - 氯 - N - 苯基苯甲酰胺、2 - 氯 - N-(2 - 氯苯基)苯甲酰胺和2 - 氯 - N-(2,3 - 二氯苯基)苯甲酰胺中观察到的具有相似键参数的情况。此外，酰胺O原子的位置与苯甲酰环中的邻位氯原子呈顺式。酰胺基团与苯甲酰环形成的二面角为59.8 (1)°，而苯甲酰环和苯胺环形成的二面角为8.1 (2)°。分子通过N - H⋯O氢键连接成沿b轴延伸的无限链。
