In the title compound, C11H11NO3S2, the S—Csp2 bonds are shorter [1.746 (3) and 1.750 (2) Å] than the S—CH3 bonds [1.794 (3) and 1.806 (3) Å], which we attribute to dπ inter­actions between the S atoms and the C=C bond. The 1,1-bis­(methyl­sulfan­yl)-3-oxo­propyl­ene fragment and the 4-nitro­phenyl group are both almost planar, with the largest deviations from their mean planes being 0.053 (1) and 0.017 (2) Å, respectively. The dihedral angle between the two planes is 35.07 (7)°. Mol­ecules in the crystal are linked into a three-dimensional network by C—H⋯S and C—H⋯O hydrogen bonds.

Comment top

Heterocyclic ketene aminals are important and versatile starting materials for the synthesis of a wide variety of fused heterocycles (Huang & Wang, 1994). In this paper, we report the crystal structure of the title compound, which is a precursor of heterocyclic ketene aminals. The shortening of bonds C3—S1 [1.746 (3) Å] and C3—S2 [1.750 (2) Å] with respect to bonds C1—S1 [1.794 (3) Å] and C2—S2 [1.806 (3) Å] is attributed to d-π interactions between sulfur and the C=C bond. The dihedral angle between 4-nitrophenyl group and (C1, C2, S1, S2, C3, C4, C5, O1) is 35.07 (7)°. In the structure of the title compound, molecules are connected through intermolecular C—H···S and C—H···O hydrogen bonding (Table 1) into a three-dimensional network.

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.
