The conformation of the N-H bond in the structure of the title compound (3NPDCA), C(8)H(6)Cl(2)N(2)O(3), is anti to the meta-nitro group, similar to that in the structures of 2-chloro-N-(3-nitro-phen-yl)acetamide (3NPCA) and 2,2,2-trichloro-N-(3-nitro-phen-yl)acetamide (3NPTCA), and the meta-chloro group in 2,2-dichloro-N-(3-chloro-phen-yl)acetamide (3CPDCA). The geometric parameters of 3NPDCA are similar to those of 2,2-dichloro-N-phenyl-acetamide, 3CPDCA, 3NPCA, 3NPTCA and other acetanilides. Inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains running along the b axis.
标题化合物（3NPDCA），即C(8)H(6)Cl(2)N(2)O(3)的结构中，N-H键的构象与间硝基呈反式，类似于2-氯-N-(3-硝基苯基)乙酰胺（3NPCA）和2,2,2-三氯-N-(3-硝基苯基)乙酰胺（3NPTCA）的结构，以及2,2-二氯-N-(3-氯苯基)乙酰胺（3CPDCA）中的间氯基团。3NPDCA的几何参数与2,2-二氯-N-苯基乙酰胺、3CPDCA、3NPCA、3NPTCA及其他乙酰苯胺类化合物的几何参数相似。分子间的N-H⋯O氢键将分子连接成沿b轴延伸的链。
