A simple and general approach to the synthesis (from commercial precursors) of eight out of nine possible (benzo[d]imidazol-2-yl)methanols fluorinated on the benzene ring is reported. Molecular and crystalline structures of most compounds were solved by X-ray diffraction analysis. This made it possible to reveal the influence of the number and arrangement of fluorine atoms in the benzene cycle on the formation of intermolecular hydrogen bonds. It was found that the more fluorine atoms are present in a compound, the higher the dimensionality of the H-bonded structure is. Moreover, the presence of fluorine atoms in the synthesized compounds leads to the emergence of C–F…π interactions affecting crystal packing. The synthesized fluorinated (benzo[d]imidazol-2-yl)methanols may serve as excellent bench compounds for the synthesis of a systematic series of fluorine-containing derivatives to study structure–property correlations in various fields of research from medicine to materials science.
