Crystal structure of flufenoxuron: a benzoyl­urea pesticide

The title compound, C(21)H(11)ClF(6)N(2)O(3) (systematic name: 1-{4-[2-chloro-4-(trifluoromethyl)phenoxy]-2-fluorophenyl}-3-(2,6-di­fluoro­benzo­yl)urea), is a benzoyl­urea pesticide. The dihedral angles between the central fluoro­benzene ring and the terminal di­fluoro­phenyl ring and chloro­phenyl ring system are 62.15 (5) and 88.03 (5)°, respectively. In the crystal, N—H⋯O hydrogen bonds link adjacent mol­ecules, forming R (2) (2)(8) inversion dimers that pack into loop chains along the a-axis direction by short F⋯F contacts [2.729 (2) Å]. In addition, the chains are linked by weak C—H⋯π and π–π inter­actions [inter-centroid distances = 3.661 (2) and 3.535 (12) Å], resulting in a three-dimensional architecture.
