The asymmetric unit of the title compound, C34H28S8, contains two crystallographically independent half-molecules. The molecules lie on centers of inversion. The four benzene rings of each molecule are substantially twisted from the planes of the 1,3-dithiole rings, forming dihedral angles of 43.6 (2) and 61.4 (1)° in one molecule and 54.2 (1) and 65.2 (1)° in the other.
