Abstract
Four molecular capsules based on three different cucurbit[5]urils, which are Dimethyl cucurbit[5]uril (DMeQ[5]), decamethylcucurbit[5]uril (Me10Q[5]) and the normal cucurbit[5]uril, were synthesized and structurally characterized by single-crystal X-ray diffractions. They are {[Gd2(H2O)9][DMeQ[5]@Cl]}5+·5Cl−·13(H2O) (1), {[Nd2(H2O)8Cl][Me10Q[5]@Cl]}4+·4Cl−·9(H2O) (2), {K(H2O)2Cl·{[[Dy2(H2O)6Cl][Q [5]@Cl]}2}8+·2{[Dy2(H2O)7Cl][Q[5]@Cl]}4+·16Cl−·44(H2O) (3) and 2{[Y2(H2O)8][Me 10Q[5]@Cl]}5+·10Cl−·48(H2O) (4). In the crystal structure of these compounds, molecular capsules included a Cl− anion and lidded with lanthanide cations were observed.
