title: N-{[2,5-Dichloro-4-(1,1,2,3,3,3-hexa-fluoro-prop-oxy)phen-yl]amino-carbon-yl}-2,6-difluoro-benzamide.
abstract: In the mol-ecule of the title compound, C(17)H(8)Cl(2)F(8)N(2)O(3), the two aromatic rings are oriented at a dihedral angle of 50.12 (3)°. Intra-molecular N-H⋯O, C-H⋯O and N-H⋯Cl hydrogen bonds result in the formation of two six- and one five-membered rings. The six-membered rings have flattened-boat conformations, while the five-membered ring adopts an envelope conformation. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers.
