(Received 21 July 2010; accepted 23 July 2010; online 31 July 2010)

In the title compound, C11H12NO4PS2, the dihedral angle between the phthalimidyl ring plane and the PS2 plane of the phospho­rodithio­ate group is 60.41 (3)°. In the crystal structure, weak inter­molecular C—H⋯O hydrogen bonds and S⋯S inter­actions [3.3825 (9) Å] contribute to the stabilization of the packing.

Comment top

Phosmet (systematic name: O,O-dimethyl S-phthalimidomethyl phosphorodithioate), is a well known organothiophosphate acaricides and isoindole organothiophosphate insecticides used on plants and animals (Song et al., 2009). However, it's crystal structure has not been reported yet.

In the title compound (Scheme 1, Fig.1), the dihedral angle between the phthalimidyl ring plane and the S1/P1/S2 plane of phosphorodithioate group is 60.41 (3)°. All bond lengths and bond angles of phosphorodithioate group are are comparable to those observed in similar structures (Baughman & Allen, 1995; Rohrbaugh et al., 1976).

In the crystal structure, as shown in Fig. 2, weak C—H···O hydrogen bonds are observed [C2—H2B···O3; H2B···O3 = 2.57 Å; C2—H2B···O3 = 128°; C2···O3 = 3.272 (2) Å; -x + 1, -y + 1, -z and C2—H2C···O4; H2C···O4 = 2.70 Å; C2—H2C···O4 = 130°; C2···O4 = 3.420 (2) Å; -x + 1, -y + 1, -z + 1]. Weak intermolecular S···S interactions with 3.3825 (9) Å also exist. These intermolecular interactions may be contribute to the stabilization of the packing.

Experimental top

The title compound was purchased from the Dr. Ehrenstorfer GmbH Company. Slow evaporation of a CH2Cl2 solution gave single crystals suitable for X-ray analysis.

Refinement top

All H-atoms were positioned geometrically and refined using a riding model with d(C—H) = 0.95 Å, Uiso = 1.2Ueq(C) for aromatic and 0.98 Å, Uiso = 1.5Ueq(C) for the d(C—H) = 0.98 Å, Uiso = 1.5Ueq(C) for CH3 groups.

Special details top

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.
