Abstract:
The title molecules, C(15)H(9)ClF(2)N(2)S and C(16)H(12)F(2)N(2)S, respectively, display the well known butterfly-like conformation with a flat thiazolobenzimidazole system. In both compounds, the mean plane through the tricyclic system is almost perpendicular to the 2,6-difluorophenyl ring. This arrangement of the aryl group is determined by two intramolecular hydrogen bonds and by an attractive F.S interaction.
