Formation of a dimeric host-guest complex via binding between a dicationic ionic liquid and a pyrogallol[4]arene macrocycle.
The crystal structure of a cocrystal comprising a complex of a bis(imidazolium) ionic liquid hosted by pyrogallol[4]arene (PgC) macrocycles is reported. Introduction of the dicationic species yields complexation by two PgC macrocycles, the resulting bilayer structure formed from alternately arranged dimeric host-guest complexes.
