A polytopic host for several cations and anions or cation/anion aggregates was previously unknown. The anion of the title (structure depicted on the right) is a host/guest system in which the “host”—the shell—consists of electrophilic and nucleophilic components. The cation/anion aggregate (NH 4 ) 2 Cl 2 , a section of the NH 4 Cl ion lattice, is incorporated as “guest”.
