To a well stirred solution of 1-methyl-3-trifluoromethyl-5-(3-chlorophenthio)- 1H-pyrazole-4-carbaldehyde oxime (4 mmol), and pyridine (5 ml) in 40 ml of dichloromethane, was added dropwise 4-chlorobenzoyl chloride (5 mmol) at room temperature. The resulting solution was heated to reflux for 7 h and cooled to room temperature. The mixture was washed with saturated brine (3 * 30 ml) and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure, the residue was separated by
on silica gel with petroleum ether/ethyl acetate (12:1 v/v) as and then recrystallized from petroleum ether/ethyl acetate acetate to give a colourless crystal.All H atoms were placed in calculated positions, with C–H = 0.93 - 0.96 Å, and included in the final cycles of
using a riding model, with Uiso(H) = 1.2-1.5 Ueq(C).As a continuation of our structural investigation of pyrazole oxime
(Dai et al., 2011), we report here the structure of the title compound (I).In (I) (Fig. 1), all bonds lengths and angles are comparable with those observed in the related compound (Dai et al., 2011). The mean planes p1 (C7/C8/C9/N2/N1), p2 (C1/C2/C3/C4/C5/C6) and p3 (C13/C14/C15/C16/C17/C18) form the following dihedral angles - p2/p1 89.5 (2)°, p3/p1 11.4 (3)°. The crystal packing shows weak intermolecular C—H···N interactions (Table 1), which link molecules into chains along the a axis.

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 a continuation of our structural investigation of pyrazole oxime esters (Dai et al., 2011), we report here the structure of the title compound (I).
In (I) (Fig. 1), all bonds lengths and angles are comparable with those observed in the related compound (Dai et al., 2011). The mean planes p1 (C7/C8/C9/N2/N1), p2 (C1/C2/C3/C4/C5/C6) and p3 (C13/C14/C15/C16/C17/C18) form the following dihedral angles - p2/p1 89.5 (2)°, p3/p1 11.4 (3)°. The crystal packing shows weak intermolecular C—H···N interactions (Table 1), which link molecules into chains along the a axis.
