Abstract
The bridged macrocyclic polyether (1b) having 9 donor oxygen atoms forms water soluble complexes of 1:1 stoicheiometry with potassium and caesium salts, however polyethers (1a) and (2a) with 8 donor oxygen atoms, having shorter bridges, give 1:2 complexes with caesium chloride while maintaining 1:1 complexes with potassium salts; in the crystalline form of a typical 1:1 complex, KCl·(2a)·n(H2O), there are discrete cations containing a potassium ion co-ordinated only by the encapsulating ligand while the chloride ions and water molecules (n is ca. 5) occupy disordered sites in columns.Keywords
