In the title compound, C(10)H(7)Cl(2)NO(3), the asymmetric unit contains four independent mol-ecules, which are linked to each other by N-H⋯O hydrogen bonds. The mol-ecular structure is stabilized by a short intra-molecular O-H⋯O hydrogen bond within each maleamic acid unit. In the crystal, the mol-ecules are linked into networks through N-H⋯O hydrogen bonds and inter-molecular C-Cl⋯O=C contacts [Cl⋯O = 3.0897 (12) and 3.0797 (13) Å].
在标题化合物C₁₀H₇Cl₂NO₃中，不对称单元包含四个独立分子，它们通过N—H⋯O氢键相互连接。每个马来酰胺酸单元内的短分子内O—H⋯O氢键使分子结构得以稳定。在晶体中，分子通过N—H⋯O氢键和分子间C—Cl⋯O=C接触 [Cl⋯O = 3.0897 (12) 和3.0797 (13) Å] 连接成网络。
