Versatile Anion–π Interactions between Halides and a Conformationally Rigid Bis(tetraoxacalix[2]arene[2]triazine) Cage and Their Directing Effect on Molecular Assembly

Abstract

Interactive halides: Bis(tetraoxacalix[2]arene[2]triazine), a conformationally rigid cage molecule of three V-shaped electron-deficient clefts, forms 1:1 complexes with fluoride (361 M−1), chloride (146 M−1) and bromide (95 M−1) in acetonitrile. Different anion–π interactions along with multiple hydrogen bonding, halogen bonding and lone-pair-electrons–π interactions directed the formation of different molecular assemblies (an example is shown here).
