title: 1-(2,6-Difluoro-benzo-yl)-3-(2,3,5-tri-chloro-phen-yl)urea.
abstract: The asymmetric unit of the title compound, C(14)H(7)Cl(3)F(2)N(2)O(2), contains two unique molecules. The 2,3,5-trichloro-phenyl ring is almost coplanar with the urea group in both molecules, whereas the 2,6-difluoro-phenyl ring is twisted from the urea plane by 54.83 (10)° in one molecule and 60.58 (10)° in the other. An intra-molecular N-H-O hydrogen bond stabilizes the mol-ecular conformation. The crystal packing is formed by inter-molecular N-H-O hydrogen bonds and F⋯F inter-actions [2.841 (2) Å].
