Synthesis of coordination complex with cucurbit [5] uril and calcium chloride and its crystal structure
Pages: 84-87

Journal: Guizhou Science

Keyword:  普通五元瓜环钙离子晶体结构分子胶囊;
Abstract: 利用单晶X-射线衍射分析方法测定了普通五元瓜环(Q5)与Ca2+在氢溴酸里形成配合物的晶体结构.结构表明Ca2+和Q5可以形成类似二聚体形式的短链,每个瓜环的空腔中都包结着溴离子,形成分子胶囊结构.通过[ZnC14]2-和游离的氯离子瓜环之间可以形成一维超分子链和网状结构.
