2-[5-(Benzo[d]thia-zol-2-yl)thio-phen-2-yl]benzo[d]thia-zole
Abstract:
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.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
