Noncovalent Interactions in Halogenated Pyridinium Salts of the Weakly Coordinating Anion [Al(OTeF(5))(4)](−)

The synthesis and the first structural characterization of the halogenated pyridinium salts [C(5)F(5)NH](+), [C(5)F(4)ClNH](+), [(C(5)F(5)N)(2)H](+), [(C(5)Cl(5)N)(2)H](+) of the weakly coordinating anion (WCA) [Al(OTeF(5))(4)](−), showing noncovalent interactions in the solid state, are presented....

Descripción
Sumario:The synthesis and the first structural characterization of the halogenated pyridinium salts [C(5)F(5)NH](+), [C(5)F(4)ClNH](+), [(C(5)F(5)N)(2)H](+), [(C(5)Cl(5)N)(2)H](+) of the weakly coordinating anion (WCA) [Al(OTeF(5))(4)](−), showing noncovalent interactions in the solid state, are presented. The salts were characterized by the multinuclear NMR and IR spectroscopy as well as X‐ray diffraction. Hirshfeld surface analysis and solid state structures reveal various intermolecular anion‐π and σ‐hole interactions between the corresponding halogenated pyridinium cations and the anion [Al(OTeF(5))(4)](−).
