Anions as guests in electroneutral host compounds that have no Lewis acid character —this has been achieved for the first time. The borane–amine adduct 1 functions as host, and examples of guests are Cl − , I − , and CN − . Prerequisite for the supramolecular inclusion of the anions is the exact preorganization of the strong BN dipoles. X(CH 2 ) 6 −
