In the title compound, C14H10N2O4S2,the furoxan heterocyclic ring and the two S atoms are almost co-planar, with a mean deviation of 0.036 Å. The bond lengths in the pentagonal ring show electron delocalization and the furoxan N—O bond length is quite short [1.211 (3) Å]. The dihedral angles between the central ring and pendant phenyl rings are 78.05 (14) and 84.28 (2)°.

The 3-phenylthio-4-phenylsulfonyl-furoxanhas been obtained according to Tosco et al. (2004).
C-bound H atoms have been placed in geometrically idealized positions (C—H = 0.93 Å), and refined as riding, with Uiso(H) = 1.2 Ueq(C).
The title compound shows a planar moiety including the two sulfur atoms and the furoxanic ring, with a mean deviation from planarity of 0.036 Å. The planar ring contains also a significant delocalization in the N2C2C1N1O1 fragment, while the O1—N2 bond is quite greater than the corresponding N1—O1 (1.461 (3) Å vs. 1.363 (3) Å). The N2—O2 bond length is quite short (1.211 (3) Å), similar however to that reported by Sorba et al. (1996) and Dutov et al. (2007).

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. |

The title compound shows a planar moiety including the two sulfur atoms and the furoxanic ring, with a mean deviation from planarity of 0.036 Å. The planar ring contains also a significant delocalization in the N2C2C1N1O1 fragment, while the O1—N2 bond is quite greater than the corresponding N1—O1 (1.461 (3) Å vs. 1.363 (3) Å). The N2—O2 bond length is quite short (1.211 (3) Å), similar however to that reported by Sorba et al. (1996) and Dutov et al. (2007).
