Novel supramolecular architectures formed by self‐assembly of three or four charged and neutral species have been prepared and characterized. In both the solution and solid states the two dibenzylammonium ions in the dicationic 1:2 complex 1 are threaded simultaneously through bis‐para‐phenylene[34]crown‐10. This macrocyclic polyether forms a 2:2 complex with α,α′‐bis(benzylammonium)‐para‐xylylene bis(hexafluorophosphate) in the solid state. (Figure Presented.)
