The title compound, C74H72S8, possesses a conformation which is unique for a per(arylthio)naphthalene in that the side chains at one of the peri positions adopt a syn arrangement, whereas all molecules of this class studied previously uniformly exhibit anti arrangements at the peri positions. This asymmetric conformation is of the previously uncategorized abbaabab type, where a and b denote side chains projecting, respectively, above and below the mean plane of the naphthalene core. A significant non-planarity of the naphthalene core is imparted by a substantial twist around its central carbon-carbon bond characterized by the symmetry-independent intra-ring torsion angles.
