چکیده انگلیسی
In this work, ab initio calculations have been performed to investigate the interaction between FnH3ânCBr (n = 0, 1, 2, 3) and HMgH at the MP2/aug-cc-pVTZ level. The results obtained from these calculations reveal the weak non-covalent Brâ¯H interactions in all complexes. The calculated interaction energies for the complexes span from â2.17 to â8.98 kJ/mol. Upon complexation, the C-Br and H-Mg bonds are both elongated. Most C-Br stretches have a small red shift, whereas the H-Mg stretch exhibits a blue shift. These complexes are stabilized by the electrostatic interaction, charge transfer interaction and polarization interaction. The halogen-bonding nature of the Brâ¯H interactions has been identified in terms of the bond critical point analysis within the theory of atoms in molecules.
