摘　　要：利用单晶X-射线衍射分析方法测定了五元瓜环与铯离子形成配合物的晶体结构,结果表明该配合物形成了以五元瓜环为"胶囊体",氯原子为"胶囊"芯材,铯离子为"胶囊盖"的"分子胶囊"结构,相邻的"分子胶囊"通过铯离子与水分子之间的配键组装形成一维超分子链,而相邻超分子链之间通过水分子、氯离子之间的氢键作用连接成二维的网状结构。A single crystal based on cucurbit[5] uril（Q[5]） with Cesium Chloride was synthesized,and structurally characterized by single crystal X-ray diffractions determination.The crystal structure of the compound shows that a chloride is encapsulated in Q[5] to form molecular capsulecaped with two cesium cations,and the capsules assembled through water molecule to form 1D supramolecular chain.And a 2D network structure was formed between adjacent supramolecular chain through water molecules,chloride ions formation hydrogen bonding interaction.
