| Coordination of Dimethylcucurbit[5]uril with Potassium and Gadolinium Cations | |
| 摘要: 利用X-射线单晶衍射技术表征了2个二甲基取代五元瓜环(DMeQ[5])与金属离子形成的配合物的晶体结构，2个配合物分别为{[K2(H2O)3DMeQ[5]}I2·5H2O (1)和{[Gd(H2O)3][K(H2O)][(NO3)@DMeQ[5]]}(NO3)3·5H2O (2)。与DMeQ[5]和钆离子形成的配合物的结构不同的是，配合物1和2中每个DMeQ[5]端口的所有羰基氧原子都和钾离子或钆离子配位，形成全封闭结构。 | |

| Abstract: Two dimethyl-substituted cucurbit[5]uril (DMeQ[5]) complexes with heterometallic potassium/gadolinium metal ions and with potassium ions only were structurally characterized by single-crystal X-ray diffractions. They are {[K2(H2O)3DMeQ[5]}I2·5H2O (1) and {[Gd(H2O)3][K(H2O)][(NO3)@DMeQ[5]]}(NO3)3·5H2O (2). Compared to the complex of DMeQ[5] with gadolinium metal ions only, both opening portals of DMeQ[5] are fully capped by potassium cations or potassium and gadolinium cation ions in these two DMeQ[5]-based complexes.
