Cylindrical calix[4]-bis-cryptand, calix[4]arene incorporating one diaza-tetraoxa-macrocyclic [18]-N₂O₄ subunit on each side of 1,3-alternate calix[4]arene framework, has been synthesized. The complexations of some alkali and ammonium cations by this macropentacycle have been studied by means of proton nuclear magnetic resonance spectroscopy.
