| Abstract: | The crystal structure of the complex phen · phen · phen] · NaBr · 2 CHCl3 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. |
