Abstract:
In recent decades, unconventional noncovalent interactions, such as Anion–π and σ-Hole interactions, have garnered significant interest within the scientific community. The field of theoretical chemistry has played a pivotal role in unraveling the underlying physical principles governing these noncovalent forces. This profound comprehension has paved the way for the anticipation of novel applications of these forces in crystal engineering and catalysis. In this presentation, we will delve into several illustrative examples of these predictions, encompassing topics such as anion–π and tetrel bonding catalysis, anion recognition, and crystal engineering.
