The crystals of the compounds [Na4(H2O)14CB[6]](bdc)2 · 13H2O (1) and [Na6(H2O)19CB[6]]-(bdc)3 ·15H2O (2) were obtained by heating an aqueous solution of sodium terephthalate (Na2bdc) and cucurbit[6]uril (CB[6]). According to the single-crystal X-ray diffraction data, the sodium aqua complexes and cucurbit[6]uril molecules form chains (in structure 1) and layered metal-organic frameworks (in structure 2). The structures of the sodium aqua complexes [Na3(H2O)10]3+ in 1 and [Na6(H2O)19]3+ in 2 have been previously unknown. When submitted to ultraviolet radiation, crystals of 1 and 2 exhibit luminescence with an emission maximum at 428 and 434 nm, respectively.

基于钠水络合物和大环空腔和葫芦[6]脲的新型配位聚合物的合成及晶体结构

化合物[Na4(H2O)14CB[6]](bdc)2·13H2O(1)和[Na6(H2O)19CB[6]]-(bdc)3·15H2O(2)的晶体是通过加热和对苯二甲酸钠 (Na2bdc) 和葫芦 [6] 脲 (CB[6]) 的水溶液。根据单晶X射线衍射数据，钠水络合物和葫芦[6]脲分子形成链状（结构1）和层状金属有机骨架（结构2）。钠水络合物 [Na3(H2O)10]3+ in 1 和 [Na6(H2O)19]3+ in 2 的结构以前是未知的。当受到紫外线辐射时，1 和 2 的晶体分别在 428 和 434 nm 处发出最大发射光。
