## Abstract We have measured the stability constants of the cryptate complexes formed by ligands **1**โ€“**4** with alkali, alkalineโ€earth, transition metal and toxic heavy metal cations. Stabilities and selectivities of complexation of the alkali and alkalineโ€earth cations are less pronounced in **1

## Abstract The cylindrical macrotricyclic ligands **1โ€“3** yield inclusion complexes, [3]โ€cryptates, with various metal cations. NMR. studies indicate the successive formation of a mononuclear and a binuclear complex. The former is probably unsymmetrical undergoing fast intramolecular cation exchan
