title: N-(2,4,5-Trichloro-phen-yl)maleamic acid.
abstract: The title compound, C(10)H(6)Cl(3)NO(3), crystallizes with two independent mol-ecules in the asymmetric unit. The mol-ecular structure is stabilized by a short intra-molecular O-H⋯O hydrogen bond within the maleamic unit. In the crystal, each mol-ecule self-associates via N-H⋯O hydrogen bonds into chains, each running along the b axis. Two short inter-molecular Cl⋯O contacts [3.1267 (15) and 3.0523 (12) Å] and C-H⋯O inter-actions inter-connect these chains into a three-dimensional network.
