Diethyl 2,2′-(tris­ulfane-1,3-di­yl)dibenzoate

The title compound, C18H18O4S3, was synthesized in the presence of chlorido­auric acid from 3H-1,2-benzodithiole-3-thione as starting material. The asymmetric unit comprises one half of the mol­ecule, the complete mol­ecule being generated by the application of twofold rotation symmetry. The two benzene rings are inclined by 81.0 (2)°. In the crystal, slipped π–π stacking inter­actions are observed between the benzene rings of neighbouring mol­ecules.
