| 摘要: 本文以六元瓜环及两种部分甲基取代六元瓜环(统称为Q[6]s)为构筑元件，合成了4个Q[6]s-Sr(Ⅱ)离子的配合物，用X射线单晶衍射方法测定了配合物的晶体结构。结果表明，Q[6]s-Sr(Ⅱ)离子配合物自组装形成不同结构的分子链，体系中存在Cl-离子时，Q[6]s-Sr(Ⅱ)离子形成配位聚合链，而只有NO3-离子存在时，形成水分子配位桥连的超分子链。 |

| Abstract: In the present work, three different cucurbit[6]urils (Q[6]s), the unsubstituted cucurbit[6]uril, 1,3,5-hexamethylcucurbit[6]uril, and symmetric tetramethyl cucurbit[6]uril were selected as the building blocks or the construction of Q[6]s-based coordination polymers. Four compounds based on the Q[6]s-Sr(Ⅱ) complexes were synthesized and characterized by single crystal X-ray diffraction. The crystal structures of the obtained compounds show a common feature of Q[6]s-Sr(Ⅱ) complex-based one dimensional supramolecular chain. In the presence of Cl- anion as a counter ion, the supramolecular chains are typical coordination polymers, while in the presence of NO3- anion as a counter ion, the formation of chain is based on share of coordinated water molecules.CCDC: 653909, 1; 977776, 2; 977778 3; 977777, 4. |
