Notes:
The title molecules, C15H9ClF2N2S and C16H12F2N2S, 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.
