Abstract

In this manuscript the ability of closo-carboranes to establish CH⋯π and BH⋯π interactions with several aromatic moieties exhibiting different electronic natures has been evaluated at the PBE0-D3/def2-TZVP level of theory. We have used the three closo isomers (ortho-, meta-, and para-) and benzene, trifluorobenzene and hexafluorobenzene as aromatic systems. Furthermore, we have used Bader's theory of “atoms in molecules” to further describe and characterize the noncovalent interactions described herein from a charge-density perspective. Finally, several biological examples retrieved from the PDB are also included, highlighting the impact of these interactions in the binding affinity of boron tracedrugs.
