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

Pyrogallol[4]arene is a macrocycle with a concave surface and 12 peripheral hydroxyl groups that mediate its self-assembly to form hexamers of octahedral symmetry in the solid state, in solution, and in the gas phase. These hexamers enclose approximately 1300 Å(3)
