چکیده
The structure of the title compound, C(18)H(10)N(2)S(3), consists of a central thio-phene ring and two terminal thia-zole rings. The two S atoms of the thia-zole rings are trans to the thio-phene S atom sulfur. The thia-zole rings are approximately coplanar with the thio-phene ring, with dihedral angles of 6.23 (11) and 4.81 (11)° between them. In the crystal, zigzag chains are formed along [010] by weak C-H⋯N inter-actions.
