The coordination and supramolecular assemblies of lanthanide cations and perhydroxycucurbit[5]uril {(HO)10Q[5]} in the presence of [SiW12O40]4– anions and transition metal salts show significant differences as the lanthanide atomic number increases. The molecular capsule (HO)10Q[5] coordinates with the light lanthanide cations Ce3+, Pr3+, Nd3+, Sm3+, Eu3+, Gd3+, and Tb3+ but does not coordinate with...
