摘　　要：通过膦配体作为辅助配体的方法,合成了一例无机阴离子与有机炔配体共保护的Ag43(t BuC≡C)24(CF3SO3)8纳米团簇。X射线单晶衍射表明团簇金属内核为同轴的Ag@Ag12@Ag30三层核壳结构,是一例无机含氧阴离子参与配位的含零价银的纳米团簇。此外,紫外可见吸收和荧光光谱分别发现其存在表面等离子共振(surface plasmon resonance,SPR)效应和配体到金属的电荷转移(ligand-to-metal charge transfer,LMCT)现象。An inorganic oxyanion and alkynyl protected nanocluster,Ag43(tBuC≡C)24(CF3SO3)8,was successfully synthesized by aphosphine-mediated approach.Single crystal X-ray diffraction revealed that the 43metal atoms in the cluster were arranged as a three-concentric-shell Ag@[e-mail] the best of our knowledge,this is a Ag(0)nanocluster protected by inorganic oxyanions.In addition,the UV-Vis absorption and fluorescence properties of Ag43cluster revealed the existence of surface plasmon resonance(SPR)effect and the ligand-to-metal charge transfer(LMCT),respectively.
