In this article , an MP2 computational study was performed for the XF-TF3CN series of complexes involving a strongly bound LiF-TTF 3CN molecular subunit, characterised by a strong bonding motif with an Si-F (or Ge-F) bond perpendicular to the LiF molecule.Abstract:
An MP2 computational study was undertaken for the XF···LiF-TF3CN (X = Li, H, Cl: T = Si, Ge) and LiF-TF3CN···XF (T = Si, Ge; XF = BeF2, BF3, SF2, PH2F, SiH3F, LiF, HF, ClF) series of complexes involving a strongly bound LiF-TF3CN molecular subunit, characterised by a strong bonding motif with an Si-F (or Ge-F) bond perpendicular to the LiF molecule. The effect of attachment of XF, to either the LiF or the CN end of the LiF-TF3CN moiety, was investigated and rationalised with the aid of the natural bond orbital (NBO) analyses and localised molecular orbital-energy decomposition analyses (LMO-EDA). These analyses allow for a comparison of the bonding features in these complexes and the relative strengths of the noncovalent interactions introduced by the model Lewis acids XF.

TL;DR: In this article , the authors examined how various aspect of the base on which the N atom is located affect the strength and other properties of complexes formed with Lewis acids FH, FBr, F2Se, and F3As that respectively encompass hydrogen, halogen, chalcogen, and pnicogen bonds.

Halogen bonding: the σ-hole
TL;DR: In this paper, the authors carried out a natural bond order B3LYP analysis of the molecules CF(3)X, with X = F, Cl, Br and I. The results showed that the Cl and Br atoms in these molecules closely approximate the [Formula: see text] configuration, where the z-axis is along the R-X bond.
