Graphical Abstract Abstract Halogen bonds (XBs) are non-covalent R-X···B interactions where heavy halogens (X = Cl, Br, I) act as electrophilic species interacting with Lewis bases (B). This highly directional type of interaction is mostly explained by the existence of a positive region on the molecular electrostatic potential located at the tip of the halogen (called σ-hole), arising from polarization of the R-X covalent bond. Following the recognition of the significance of XBs indoi:10.3390/mol2net-03-05075 fatcat:bw7dhajhobgd5ep26do43eir5y
