In the crystal structure of the title compound, C(10)H(9)Cl(2)NO(3), the conformations of the amide O atom and the carbonyl O atom of the acid segment are anti to the H atoms of the adjacent -CH(2) groups. The C=O and O-H bonds of the acid group are in relatively rare anti positions with respect to each other. This is an obvious consequence of the concerted effects of both the all-anti mol-ecular conformation and the intermolecular hydrogen bond donated to the amide carbonyl group. In the crystal, mol-ecules are packed into infinite chains through inter-molecular N-H⋯O and O-H⋯O hydrogen bonds.
在标题化合物C(10)H(9)Cl(2)NO(3)的晶体结构中，酰胺O原子和酸片段的羰基O原子的构象与相邻-CH(2)基团的H原子呈反式。酸基团的C=O键和O-H键相对于彼此处于相对罕见的反式位置。这是全反式分子构象和给予酰胺羰基的分子间氢键共同作用的明显结果。在晶体中，分子通过分子间N-H⋯O和O-H⋯O氢键堆积成无限长链。
