Cover illustration: In this compound, C7H10N+·ClO4-·C20H24O6, the protonated benzylamine cation forms a rotator-stator complex with the 18-crown-6 (1,4,7,10,13,16-hexaoxacyclooctadecane) molecule via three bifurcated hydrogen N-H...O hydrogen bonds each to two adjacent oxygen atoms of the crown ring. The complex cations form chains parallel to [011] via weak C-H...[pi] interactions parallel to [011], with the perchlorate anions located between the chains. See Wang, Li & Wang [Acta Cryst. (2011). E67, o772].
