The title molecule, C12H14ClN2O3PS, has a cis configuration with respect to the C=N bond. Intermolecular C—H⋯O interactions interconnect the molecules into chains along the c axis. The chains are further connected into a two-dimensional network parallel to the bc plane by weak π–π interactions between adjacent aromatic rings (centroid–centroid distance = 3.772Å).

Sodium, 2.30 g (0.1 mol), reacted with 50 ml of absolute ethanol in order to get sodium ethoxide solution. 15.20 g (0.1 mol) of 2-chlorophenylacetonitrile, was added dropwise to the cooled sodium ethoxide (about 278 K) and then 10.30 g (0.1 mol) of butyl nitrite was added dropwise. The mixture was stirred at room temperature for 1 h under reduced pressure until the volume was reduced to 30 ml. Then 50 ml of ethyl ether was added, and the precipitated solid was filtered off and washed with ethyl ether to afford sodium 2-chlorophenylglyoxylonitrile oxime (11.3 g, 56%). Diethyl phosphorochloridothionate, 5.70 g (0.03 mol), was added dropwise to 6.00 g (0.03 mol) of sodium 2-chlorophenylglyoxylonitrile oxime, which was suspended in 20 ml of dry acetone. The mixture was stirred for 1 h. Thin layered
using petroleum ether and ethyl acetate as expanding solvent indicated just one point. The mixture was then concentrated under reduced pressure and 50 ml of water was added to the residue. The precipitated solid that had appeared was filtered off, washed thoroughly with absolute ethanol, dried and recrystallized from petroleum ether to afford the title compound (8.9 g, yield 89%) as a white crystalline solid. The title crystals suitable for X-ray diffraction were obtained by slow evaporation of the acetone solution. The average size of the block-like crystals is 0.2 × 0.2 × 0.2 mm.The aryl and methylene H atoms were situated into idealized positions though the aryl H atoms were clearly discernible in the difference
After the with these H atoms whose parameters were fully constrained had converged the revealed that the methyl H atoms were not disordered. They were also situated into the idealized positions and constrained.

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. |

O,O-diethyl-O-(2-chlorophenylglyoxylonitrile oximino)thiophosphate (Chlorphoxim) was shown to be efficient against adult mosquitoes as well as agricultural insects (Hudson et al., 1972). It was also successfully tested against the larvae of the blackfly (Simulium damnosum), the insect vector of human onchocerciasis in West Africa (Le Berre et al., 1972). The title substance combined with niclosamide exhibited significant molluscicidal synergism against snails (Oncomelania hupensis) (Wang et al., 1996). The synthesis of the title compound has been described by Walter et al. (1973). As a part of our own studies in this area, we report here its crystal structure.
The title molecule shows a cis configuration (Fig. 1) on the C═N bond. The molecules are linked into chains along the axis c via weak intermolecular C—H···O interactions (Fig. 2, Tab. 1). The chains are further connected into a two-dimensional network via weak π-π electron interactions between the adjacent phenyl rings: The centroid-centroid distance is 3.772 Å.
