title: Picric acid-2,4,6-trichloro-aniline (1/1).
abstract: In the title adduct, C(6)H(4)Cl(3)N·C(6)H(3)N(3)O(7), the two benzene rings are almost coplanar, with a dihedral angle of 1.19 (1)° and an inter-ring centroid-centroid separation of 4.816 (2) Å. The crystal structure is stabilized by inter-molecular N-H⋯O(nitro) hydrogen bonds, giving a chain structure. In addition, there are phenol-nitro O-H⋯O inter-actions.
