چکیده
In the mol-ecule of the title compound, C(28)H(22)S(2), the two thio-phene rings are twisted with respect to the central benzene ring, making dihedral angles of 71.59 (12) and 50.71 (12)°. The two terminal benzene rings are oriented at dihedral angles of 37.59 (11) and 20.12 (11)° to their bonded thio-phene rings.
