A ditopic azacryptate proton cage.
A tosylated azacryptand readily protonates at the bridgehead amines, becoming a potential ditopic anion receptor. The in-in conformation of the amines facilitates encapsulation of two bromide guests and represents the first structural evidence that a proton cage cryptate can bind two anions internally.
