首次在多金属氧酸盐(POM)杂化体系中设计了一种烯烃桥联硫醚配体(L)，合成了一种基于POM的铜(I)-烯烃化合物[(CuIL)2(PVMoVI12O40)]·(CuIL)(1)，并用X-射线单晶衍射法对其进行了表征。观察到了L独特的烯烃配位N(η2-C═C)N模式，铜中心被σ2，π-L以口袋方式捕获，生成离散的[CuIL]+阳离子和[(CuIL)2(PVMoVI12)]-阴离子.离子晶体在非质子极性溶剂中表现出溶解性，电喷雾电离质谱仪被用来探索溶液中存在的物种的性质。结果表明，整个团簇[PVMoVI12]3-是完全存在的，所有的主峰都可以归属于同一母团的不同带电碎片。
An alkene-bridged thioether ligand (L) was designed and used for its first study within a polyoxometalate (POM) hybrid system, and a POM-based copper(I)-alkene compound [(CuIL)2(PVMoVI12O40)]·(CuIL) (1) was isolated and characterized by X-ray crystallography. A unique alkene-coordinating N(η2-C═C)N mode of L is observed, and the Cu centers are captured by σ2,π-L in a pocket fashion, giving birth to discrete [CuIL]+ cations and [(CuIL)2(PVMoVI12)]- anions. The ionic crystal exhibits solubility in aprotic polar solvents, and the electrospray ionization mass spectrometry is used to explore the nature of species present in the solution. It is found that the whole cluster [PVMoVI12]3- is completely present, and all the main peaks can be assigned to different charged fragments of the same parent cluster.
