Abstract

In the title compound, C(22)H(14)O(2)S(3), 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 benzothio-phene ring systems are asymmetrically twisted away from the attached thio-phene 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 π-π inter-actions are observed in the crystal structure.
