In the title compound, C(10)H(11)Cl(2)NO, the N-H bond is syn to the 3-methyl substituent in the aromatic ring, similar to that observed in N-(3,4-dimethyl-phen-yl)acetamide and to the 3-chloro substituent in 2,2-dichloro-N-(3,4-dichloro-phen-yl)acetamide, and contrasting with the anti conformation observed for the 3-methyl substituent in 2,2,2-trichloro-N-(3,4-dimethyl-phen-yl)acetamide. On the other hand, it is anti to the C=O bond. An inter-molecular N-H⋯O hydrogen bond links mol-ecules into infinite chains along the b axis.
在标题化合物C(10)H(11)Cl(2)NO中，N - H键与芳环中的3 - 甲基取代基呈顺式，类似于在N - (3,4 - 二甲基 - 苯基)乙酰胺中观察到的情况，也与2,2 - 二氯 - N - (3,4 - 二氯 - 苯基)乙酰胺中的3 - 氯取代基呈顺式，这与在2,2,2 - 三氯 - N - (3,4 - 二甲基 - 苯基)乙酰胺中观察到的3 - 甲基取代基的反式构象形成对比。另一方面，它与C = O键呈反式。分子间的N - H⋯O氢键将分子沿b轴连接成无限长链。
