TY - JOUR TI - About the nature of halogen bond interaction under the spatial confinement AU - Roztoczyńska, Agnieszka AU - Lipkowski, Paweł AU - Kozłowska, Justyna AU - Bartkowiak, Wojciech T2 - The Journal of Chemical Physics AB - Nowadays, much attention is put toward the description of noncovalent complexes exposed to the high pressure or embedded in confining environments. Such conditions may strongly modify the physical and chemical properties of molecular systems. This study focuses on the theoretical description of the confinement induced changes in geometry and energetic parameters of the halogen bonded FCl⋯CNF complex. A model analytical potential is applied to render the effect of orbital compression. In order to analyze the nature of halogen bond interaction, in the presence of spatial confinement, the supermolecular approach together with the symmetry-adapted perturbation theory is used. Furthermore, a thorough analysis of topological parameters, characterizing the halogen bond upon orbital compression, is performed within the quantum theory of atoms in molecules. The calculations are carried out using the ωB97x and CCSD(T) methods in connection with the aug-cc-pVTZ basis set. Among others, the obtained results indicate that the spatial confinement not only modifies the nature of halogen bond interaction but also induces the appearance of a completely new form of the studied FCl⋯CNF system.
