The title compound, C6H11N2O4PS3, crystallizes with two independent molecules in the The dihedral angles between the thiadiazole ring planes and the PS2 planes of the phosphorodithioate group are 86.51 (5) and 56.33 (5)° in the two molecules. In the crystal, weak intermolecular S⋯S [3.570 (8) Å] interactions and C—H⋯O and C—H⋯N hydrogen bonds contribute to the stabilization of the packing.

The title compound was purchased from the Dr. Ehrenstorfer GmbH Company. Slow evaporation of a solution in CH2Cl2 gave single crystals suitable for X-ray analysis.
All H-atoms were positioned geometrically and refined using a riding model with d(C—H) = 0.99 Å, Uiso = 1.2Ueq(C) for CH2 and d(C—H) = 0.98 Å, Uiso = 1.5Ueq(C) for CH3 groups.

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. |

Methidathion (systematic name: S-2,3-dihydro-5-methoxy-2-oxo-1,3,4- thiadiazol-3-ylmethyl O,O-dimethyl phosphorodithioate), is one of the most widely used organophosphate insecticides in agriculture and public health programmes (Altuntas et al. 2002). However it's crystal structure has not been reported yet.
In the title compound (Scheme 1, Fig. 1), crystallizes with two independent molecules in the asymmetric unit. The dihedral angles between the thiadiazol ring planes and the PS2 planes of the phosphorodithioate group are 86.51 (5)° and 56.33 (5)° in the two molecules. All bond lengths and bond angles are normal and comparable to those observed in similar structures (Rohrbaugh et al. 1976).
In the crystal structure, as shown in Fig. 2, weak intermolecular C—H···O, C—H···N hydrogen bonds (Table 1) and S···S interactions with 3.3372 (8) Å are observed (Table 1). These intermolecular interactions may be contribute to the stabilization of the packing.
