The title compound, C21H11ClF6N2O3 (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 R22(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.
Keywords: crystal structure; benzoylurea; pesticide; N—H⋯O hydrogen bonds; C—H⋯π interactions; π–π interactions.

The title compound was purchased from the Dr. Ehrenstorfer GmbH Company. Slow evaporation of a solution in CH2Cl2 gave single crystals suitable for X-ray analysis.
All H-atoms were positioned geometrically and refined using a riding model: N—H = 0.88 Å, Uiso = 1.2Ueq(C) C—H = 0.95 Å, with Uiso = 1.2Ueq(N,C).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Flufenoxuron is a benzoylurea pesticide and acts as an insect growth regulator and chitin synthesis inhibitor. It is used to control immature stages of insects and phytophagous mites on fruits and vegetables (Salokhe et al., 2006; Kamel et al., 2007) and its crystal structure is reported on herein.
In th e title compound, Fig. 1, 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. All bond lengths and bond angles are normal and comparable to those observed in the crystal structure of a similar compound (Liu et al., 2008).
In the crystal, Fig. 2, molecules are linked by a a pair of urea N—H···O hydrogen bonds (Table 1), forming inversion dimers with an R22(8) ring motif. In addition, a short F···F contact [F2···F5i, 2.729 (2) Å] links the dimers into one-dimensional chains extending along [100]. In addition, a weak intermolecular C—H···π interaction [C2—H2A···Cg2ii, 3.611 (2) Å] and π–π interaction between the terminal chlorophenyl ring systems [Cg3···Cg3iii, 3.535 (12) Å] are present (Cg2 and Cg3 are the centroids of the C9-C14 and C15-C20 rings, respectively) [for symmetry codes: (i), -x + 1, -y + 1, -z + 1, (ii), x, y + 1, z, and (iii), -x + 2, -y + 1, -z + 2].
