The Halogen Bond
The halogen bond occurs when there is evidence of a net attractive interaction between an electrophilic region associated with a halogen atom in a molecular entity and a nucleophilic region in another, or the same, molecular entity. In this fairly extensive review, after a brief history of the interaction, we will provide the reader with a snapshot of where the research on the halogen bond is n...
متن کاملA Catenane Assembled through a Single Charge-Assisted Halogen Bond**
Interlocked molecules have captured chemists imagination owing to their nontrivial topology and the promise of their potential nanotechnological uses as molecular machines and in chemical sensor applications. The synthesis of such sophisticated architectures is a challenge, and as a consequence this has necessitated the implementation of imaginative cation, anion, and neutral templation methodo...
متن کاملEvidence for Halogen Bond Covalency in Acyclic and Interlocked Halogen-Bonding Receptor Anion Recognition
The synthesis and anion binding properties of novel halogen-bonding (XB) bis-iodotriazole-pyridinium-containing acyclic and [2]catenane anion host systems are described. The XB acyclic receptor displays selectivity for acetate over halides with enhanced anion recognition properties compared to the analogous hydrogen-bonding (HB) acyclic receptor. A reversal in halide selectivity is observed in ...
متن کاملHydrogen bonding vs. halogen bonding: the solvent decides.
Control of intermolecular interactions is integral to harnessing self-assembly in nature. Here we demonstrate that control of the competition between hydrogen bonds and halogen bonds, the two most highly studied directional intermolecular interactions, can be exerted by choice of solvent (polarity) to direct the self-assembly of co-crystals. Competitive co-crystal formation has been investigate...
متن کاملNew Type of Halogen Bond: Multivalent Halogen Interacting with π- and σ-Electrons.
MP2/aug-cc-pVTZ calculations were performed for complexes of BrF₃ and BrF₅ acting as Lewis acids through the bromine centre, with species playing a role of Lewis base: dihydrogen, acetylene, ethylene, and benzene. The molecular hydrogen donates electrons by its σ-bond, while in remaining moieties-in complexes of hydrocarbons; such an electron transfer follows from π-electrons. The complexes are...
