Comment
Pyrethroids have a high potential for biological activity with low toxicity and good environmental compatibility. They have been widely used in making pesticides (Chen & Yu, 1991; Sun et al., 2008). In a continuation of our studies of the biological activities of pyrethroids, we have obtained a colourless crystalline compound, whose structure has been confirmed by single-crystal X-ray diffraction. The crystal structures of two similar compounds have already been published (Sun, Shen, Rao et al., 2006; Sun, Shen, Zheng et al., 2006).
The molecular structure of the title compound is illustrated in Fig. 1. Atoms N1, C2, C3, N2 and C1 are approximately planar, the largest deviation from this plane being 0.025 (3) Å for atom N1. The cyclopropane ring (C5—C7) forms dihedral angles of 89.49 (22) ° and 64.07 (21) ° with the least-squares planes of the C8, C9, C6 grouping and the imidazolidine ring, respectively. In the crystal structure, intermolecular C—H···O hydrogen bonds are observed. A short intermolecular contact of O3···C3 = 3.02 Å is present.
Experimental
The title compound was synthesized according to the published procedure (Sun et al., 2008). A solution of the compound in ethanol was concentrated gradually at room temperature to afford colourless blocks.
Refinement
H atoms were included in calculated positions and refined using a riding model. Csp2—H = 0.93 Å, Cmethyl—H = 0.96 Å, Cmethylene—H = 0.97 Å and Cmethine—H = 0.98 Å. Uiso(H) = xUeq(C), where x = 1.5 for methyl H and 1.2 for all other H atoms.

Special details
| 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. |
