The 1,3,5-oxadiazinane ring in the title compound, C12H14F2N4O3, has a conformation intermediate between half-chair and screw-boat. The is stabilized by weak intermolecular C—H⋯O hydrogen bonds. Weak π–π interactions are indicated by the relatively long centroid–centroid distance of 3.9199 (12) Å and interplanar distance of 3.803 Å between symmetry-related benzene rings from neighbouring molecules.

1-(1-bromoethyl)-2,4-difluorobenzene 4.5 g (20.0 mmol),(Z)-3-methyl-N– nitro-1,3,5-oxadiazinan-4-imine 3.2 g (20.0 mmol), potassium carbonate 2.8 g (20.0 mmol) and acetonitril 20 g were charged in a flask equipped with stirrer, water separator and reflux condenser. The mixture was heated to reflux for 4 h. Upon cooling at room temperature. The reaction mixture was filtered, and the solution was concentrated under reduced pressure to give the title compound (I) 4.5 g (76% yield). (Gottfied, et al., 2001). Single crystals suitable for X-ray measurement were grown by slow evaporation of an ethanol solution of (I).
All H atoms were fixed geometrically and treated as riding with C—H = 0.95Å (aromatic), 0.98 Å (methyl), 0.99 Å (methylene) and 1.0 Å (methine) with Uiso(H) = 1.2Ueq(C) or Uiso(H) = 1.5Ueq(methyl).
As an important type of insecticides, oxadiazine compounds are highly efficient and of low toxicity (Gsell, et al., 1998). Lots of similar insecticides compounds were synthesized with the title compounds (I) (Maienfisch, et al., 1994). We report the synthesis and
of the title compound, (I).The conformation of the 1,3,5-oxadiazinane ring in(I)is intermediate between half-chair and screw-boat with puckering parameters (Cremer & Pople, 1975): Q= 0.5303 (12)Å; θ= 59.14 (13)°; φ= 329,54 (15)°. The benzene ring forms dihedral angles of 74.84 (3)° and 87.30 (2)° with the mean plane of the oxadiazine ring. The bond lengths and angles of the oxadiazine rings are in a good agreement with those reported previously (Chopra, et al., 2004). The N=C bond length [N3=C2 = 1.3804 (2) Å] are close to the value reported in the literature (Kang, et al.,2008).
The structure is stabilized by hydrogen bonds of C-H···O type. And with a π-π stacking between symmetry related phenyl rings with a centroid-to-centroid distance of 3.9199 (12)Å and interplanar distance of 3.803Å resulting in a 0.951Å slippage.

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. |

As an important type of insecticides, oxadiazine compounds are highly efficient and of low toxicity (Gsell, et al., 1998). Lots of similar insecticides compounds were synthesized with the title compounds (I) (Maienfisch, et al., 1994). We report the synthesis and crystal structure of the title compound, (I).
The conformation of the 1,3,5-oxadiazinane ring in(I)is intermediate between half-chair and screw-boat with puckering parameters (Cremer & Pople, 1975): Q= 0.5303 (12)Å; θ= 59.14 (13)°; φ= 329,54 (15)°. The benzene ring forms dihedral angles of 74.84 (3)° and 87.30 (2)° with the mean plane of the oxadiazine ring. The bond lengths and angles of the oxadiazine rings are in a good agreement with those reported previously (Chopra, et al., 2004). The N=C bond length [N3=C2 = 1.3804 (2) Å] are close to the value reported in the literature (Kang, et al.,2008).
The structure is stabilized by hydrogen bonds of C-H···O type. And with a π-π stacking between symmetry related phenyl rings with a centroid-to-centroid distance of 3.9199 (12)Å and interplanar distance of 3.803Å resulting in a 0.951Å slippage.
