“…There are two relevant papers. Berryman et al reported the synthesis and anion-binding properties of receptor 1 (2,6-bis(4-ethynylpyridinyl)-4-fluoroaniline) which can act as a halogen donor, trapping a wide variety of anions (Cl − , Br − , I − , SCN − , NO 3 − , HSO 4 − , H 2 PO 4 − and ReO 4 − ) [40] (Scheme 1). The presence of intramolecular N–H···I hydrogen bonds (HBs) increases the strength of the I···anion halogen bonds (XBs).…”

Cooperative Effects in Weak Interactions: Enhancement of Tetrel Bonds by Intramolecular Hydrogen Bonds

et al. 2019

A series of silyl and germanium complexes containing halogen atoms (fluorine and chlorine atoms) and exhibiting tetrel bonds with Lewis bases were analyzed by means of Møller-Plesset computational theory. Binding energies of germanium derivatives were more negative than silicon ones. Amongst the different Lewis bases utilized, ammonia produced the strongest tetrel bonded complexes in both Ge and Si cases, and substitution of the F atom by Cl led to stronger complexes with an ethylene backbone. However, with phenyl backbones, the fluorosilyl complexes were shown to be less stable than the chlorosilyl ones, but the opposite occurred for halogermanium complexes. In all the cases studied, the presence of a hydroxyl group enhanced the tetrel bond. That effect becomes more remarkable when an intramolecular hydrogen bond between the halogen and the hydrogen atom of the hydroxyl group takes places.

“…Initially, halogen bonding had primarily been explored in crystal engineering [16][17] and in the gas phase; [18][19] however, further investigation of these interactions have focused on their efficacy in solution phase as well. [20][21][22][23] Halogen bonding interactions are comparable in strength to those of hydrogen bonding, and furthermore, they demonstrate a surprising resilience to interference from competitive, polar solvents. [24][25][26] These attributes have generated a growing interest in halogen bonding from the supramolecular community over the past 20 years.…”
