Abstract

Aqueous solutions of sodium p-sulfonatocalix[4]arene, 18-crown-6 and lanthanum(III) trichloride at pH 2.5 afford the 'ferris wheel' type supercation: [{Ln³⁺ proper subset (18-crown-6)(OH₂)₃} intersection [(p-sulfonatocalix [4]arene^4- + 2H⁺)}]⁺ isolated as the chloride with numerous waters of crystallisation.
