3-Phenylsulfanyl-4-phenylsulfonyl-1,2,5-oxadiazole 2-oxide

Abstract

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)°.
