The crystal structure of the complex [phen · phen · phen] · NaBr · 2 CHCl 3 of the macrobicyclic ligand 1 has been determined. The complex is of cryptate type, the Na + cation being contained in the molecular cavity of 1 and coordinated to all eight N‐atoms. The ligand has a propeller shape and interconverts in solution between the two enantiomeric helical forms.
