چکیده مقاله:
When R is sufficiently electron withdrawing, the fluorine in the R-F molecules could interact with electron donors (e.g. ammonia) and form a non-covalent bond (F⋯N). Inasmuch as there are fundamental differences between these interactions and halogen bonds of iodine, bromine and chlorine, the term “fluorine bond” is preferred for describing these type of interactions. Natural energy decomposition analysis (NEDA) and interacting quantum atoms (IQA) methods reveal that fluorine and halogen bonds are different in their geometrical preference. In contrast to the halogen bonds (R-X⋯Y) that are highly directional and the R-X-Y angle tends to be linear, fluorine bonds are not directional.
