十甲基五元瓜环与几种金属离子配合物的晶体结构

Crystal Structure of the Decamethylcucurbit[5]uril Complexes with Some Metal Ions

合成了3个十甲基五元瓜环(Me10Q[5])分别与铷离子、铈离子水合物相互作用形成的配合物以及四氯锌根离子存在下形成的单晶体,并测定了其单晶结构。3个配合物均形成以Me10Q[5]为"胶囊体",水分子为"胶囊"芯材,金属离子或水分子为"胶囊盖"的"分子胶囊"结构,并通过配键或氢键组装形成一维超分子链结构实体。

Three single crystals based on decamethylcucurbit[5]uril （Mel0Q[5]） with Rb（H2O）3^＋, Ce（H2O）7^3＋ complex cations and in the presence of ZnCl4^2- complex cations were synthesized and structurally characterized by single-crystal X-ray structure determination. The crystal structure of these complexes showed that Water molecule were encapsulated in Me10Q[5] to form molecular capsules caped with metal ions or water molecules, and the capsules assembled through coordination or hydrogen bonding to form 1D supramolecular chains.
