Abstract: In the title compound, C₂₂H₁₄O₂S₃, the dioxane ring is disordered over two sites [site occupancies = 0.623 (3) and 0.377 (3)]; both components adopt half-chair conformations. The two benzothiophene ring systems are asymmetrically twisted away from the attached thiophene ring [dihedral angles = 20.57 (3) and 6.70 (3)°] and are oriented at an angle of 26.83 (3)°. No significant hydrogen bonding or - interactions are observed in the crystal structure.
