Etude des interactions halogène...X (X = halogène ou base de Lewis) à partir des mesures diffraction des rayons-X à haute résolution

Abstract : Halogen bonding is a highly directional intermolecular interaction. It is observed in systems C-Hal°°°X, where the halogen atom (Hal) is bound to a carbon atom and interacts with another halogen (X = Hal) or a Lewis base (X = Lewis base). The main objective of this thesis is to better understand these interactions. The thesis is mainly devoted to the study of the electron density and the electrostatic potential of halogenated compounds by high resolution X-ray diffraction. In this work, four chlorinated compounds, containing interactions Hal°°°X (Hal = Cl, X = Cl, O, H, C[pi]) were analyzed in their crystalline phase to study the halogen bond. Among the most important results from this work, we report the experimental determination of the anisotropic electronic distribution of the halogen atom. This anisotropy generates electrophilic and nucleophilic regions around the halogen nucleus that are responsible for the interaction that this kind of atom establishes with the environment.
