Three barrel-shaped artificial molecular capsules 1-3, based on normal cucurbit[5]uril (Q[5]) and decamethylcucurbit[5]uril (Me10Q[5]), were synthesized and structurally characterized by single-crystal X-ray diffraction. Encapsulation of a chlorine anion in the cavity of a Q[5] or Me10Q[5] to form closed a molecular capsule with the coordinated metal ions or coordinated metal ions and water molecules in the crystal structures of these compounds is common. The three complexes [Pr2(C30H30N20O10)Cl3(H2O)13]3+ 3 Cl- x 5 H2O (1), [Sr2(C40H50N20O10)(H2O)4Cl]3+ 3 Cl- x 2 (HCl) 19 H2O (2) and [K(C40H50N20O10)(H2O)Cl] x [Zn(H2O)2Cl2] x [ZnCl4]2- x 2 (H3O)+ x 8 H2O (3) all crystallize as isolated molecular capsules.
基于普通葫芦[5]脲（Q[5]）和十甲基葫芦[5]脲（Me10Q[5]）合成了三种桶状人工分子胶囊1-3，并通过单晶X射线衍射对其结构进行了表征。在这些化合物的晶体结构中，Q[5]或Me10Q[5]的空腔中包封一个氯离子，与配位金属离子或配位金属离子和水分子形成封闭的分子胶囊是常见的。三种配合物[Pr2(C30H30N20O10)Cl3(H2O)13]3+ 3 Cl- x 5 H2O（1）、[Sr2(C40H50N20O10)(H2O)4Cl]3+ 3 Cl- x 2 (HCl) 19 H2O（2）和[K(C40H50N20O10)(H2O)Cl] x [Zn(H2O)2Cl2] x [ZnCl4]2- x 2 (H3O)+ x 8 H2O（3）均以孤立的分子胶囊形式结晶。
