| pubmed-article:21580966 | pubmed:abstractText | 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]. | lld:pubmed |
