The title compound (systematic name: 1-{3,5-dichloro-4-[3-chloro-5-(trifluoromethyl)pyridin-2-yloxy]phenyl}-3-(2,6-difluorobenzoyl)urea), C20H9Cl3F5N3O3, is a benzoylphenylurea insecticide. The dihedral angles between the planes of the central dichlorophenyl and the terminal difluorophenyl and chloropyridyl rings are 79.51 (6) and 78.84 6)°, respectively. In the crystal, pairs of N—H⋯O hydrogen bonds link adjacent molecules, forming R22(8) inversion dimers. In addition, the dimers are linked by short F⋯Cl [3.1060 (16) Å] and Cl⋯Cl [3.2837 (7) Å] contacts, as well as weak intermolecular π–π interactions [ring centroid separation = 3.6100 (11) and 3.7764 (13) Å], resulting in a two-dimensional architecture parallel to (111).
Keywords: crystal structure; chlorfluazuron; urea; insecticidal properties; Cl⋯Cl contacts.

The title compound was purchased from the Dr. Ehrenstorfer GmbH Company. Slow evaporation of a solution in CHCl3 gave single crystals suitable for X-ray analysis.
All H-atoms were positioned geometrically and refined using a riding model with d(C—H) = 0.95 Å, Uiso = 1.2Ueq(C) for aromatic C—H and d(N—H) = 0.88 Å, Uiso = 1.2Ueq(C) for urea group.
Chlorfluazuron, C20H9Cl3F5N3O3, is a benzoylphenylurea which has been recognized as one of the promising insecticides with great potential for use in controlling insect attack on a broad range of fruits and vegetables (Lee et al., 2013; Choi et al., 2011). Its
is reported herein. In this compound (Scheme 1, Fig. 1), the dihedral angles between the central dichlorophenyl and the terminal difluorophenyland chloropyridyl rings are 79.51 (6) and 78.84 (6)°, respectively. All bond lengths and bond angles are normal and comparable to those observed in the of a similar compound (Jeon et al., 2014).The π–π stacking interactions [Cg1···Cg3iv = 3.7764 (13)Å. Cg1 and Cg3 are the centroids of the C1—C2—C3—C4—C5—C6 and C15—C16—C17—C18—C19—N3 rings, respectively. Cg2···Cg2ii = 3.6100 (11) Å. Cg2 is the centroid of the C9—C10—C11—C12—C13—C14 ring. (Symmetry codes: (ii), -x + 1, -y + 2, -z + 1; (iii) -x + 1, -y + 1, -z + 1 and (iv) x, y + 1, z - 1)], resulting in a two-dimensional architecture parallel to the (111) plane.

In addition, the dimers are linked by short F2···Cl3ii [3.1060 (16) Å] and Cl1···Cl1iii [3.2837 (7) Å] contacts as well as two weak intermolecular offsetFor information on the insecticidal properties of the title compound, see: Choi et al.

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. |

Chlorfluazuron, C20H9Cl3F5N3O3, is a benzoylphenylurea which has been recognized as one of the promising insecticides with great potential for use in controlling insect attack on a broad range of fruits and vegetables (Lee et al., 2013; Choi et al., 2011). Its crystal structure is reported herein. In this compound (Scheme 1, Fig. 1), the dihedral angles between the central dichlorophenyl and the terminal difluorophenyland chloropyridyl rings are 79.51 (6) and 78.84 (6)°, respectively. All bond lengths and bond angles are normal and comparable to those observed in the crystal structure of a similar compound (Jeon et al., 2014).
The crystal structure, (Fig. 2), is stabilized by N—H···O hydrogen bonds (Table 1), forming R22(8) inversion dimers. In addition, the dimers are linked by short F2···Cl3ii [3.1060 (16) Å] and Cl1···Cl1iii [3.2837 (7) Å] contacts as well as two weak intermolecular offset π–π stacking interactions [Cg1···Cg3iv = 3.7764 (13)Å. Cg1 and Cg3 are the centroids of the C1—C2—C3—C4—C5—C6 and C15—C16—C17—C18—C19—N3 rings, respectively. Cg2···Cg2ii = 3.6100 (11) Å. Cg2 is the centroid of the C9—C10—C11—C12—C13—C14 ring. (Symmetry codes: (ii), -x + 1, -y + 2, -z + 1; (iii) -x + 1, -y + 1, -z + 1 and (iv) x, y + 1, z - 1)], resulting in a two-dimensional architecture parallel to the (111) plane.
