In the title molecule, C16H14ClF6NO, the cyclopropane ring forms a dihedral angle of 70.82 (18)° with the benzene ring. The torsion angles about the ethylene and amide bonds are −2.2 (5) (Cl—C—C—C) and 0.8 (5)° (O—C—N—C). A supramolecular chain propagated by glide symmetry along [001] and mediated by N—H⋯O hydrogen bonds is observed in the crystal packing.

The title compound was synthesized according to the literature procedure (Sun et al., 2007). A solution of the compound in ethanol was concentrated gradually at room temperature to afford colourless blocks.
The H-atoms were placed in calculated positions [N—H = 0.86 Å; C—H = 0.93 to 0.98 Å, Uiso(H) = 1.2Ueq(C,N)] and were included in the
in the riding model approximation. The CF3 group was disordered and modelled over two positions of equal weight.Data collection: SMART (Bruker, 1997); cell

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. |

Pyrethroids have a high potential for biological activity with low toxicity and good environmental compatibility. These have been widely used in pesticides (Chen et al., 1991; Sun et al., 2007, 2008). In continuation of our studies of biological activities in pyrethroids, we have obtained a colourless crystalline compound, (I). The structure was confirmed by single-crystal X-ray diffraction.
The molecular structure of (I) is illustrated in Fig. 1. In (I), the cyclopropane ring (C4—C6) forms dihedral angles of 89.70 (23) and 70.82 (18)° with the least-squares planes of the (C5,C7,C8) plane and the phenyl ring, respectively. The Cl1—C2—C3—C4 and O1—C9—N1—C10 torsion angles are -2.2 (5) and 0.8 (5)°, respectively. A supramolecular chain propagated by glide symmetry along [001] and mediated by N—H···O hydrogen bonds, Table 1, is observed in the crystal packing.
