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