6-Bromo-2-methyl-sulfanyl-1,3-benzo-thia-zole.
The title mol-ecule, C(8)H(6)BrNS(2), is almost planar with a dihedral angle of 0.9 (1)° between the benzene and thia-zole rings. The values of the geometry-based index of aromaticity (HOMA) and the nucleus-independent chemical shift (NICS) for the two cyclic fragments of the title mol-ecule are 0.95 and -9.61, respectively, for the benzene ring, and 0.69 and -7.71, respectively, for the thia-zole ring. They show that the benzene ring exhibits substanti-ally higher cyclic π-electron delocalization than the thia-zole ring. Comparison with other similar benzothia-zole fragments reveals a similar trend.
