首次观察到结构明确的Ag 2S分子纳米团簇的发光。AgSBut/AgBF_4与N_2H_4在甲醇中反应得到具有核壳结构的四价阳离子簇合物[Ag_（62）S_（13）（SBut）（32）]（BF_4）（4）。[Ag 14 S13]核的14个银（I）中心呈面心立方排列，每个边缘由S2-配体桥接;核通过Ag-S键和Ag中心点Ag相互作用进一步连接到[Ag-48（SBut）（32）]壳。这种新颖的团簇在室温下在固态和溶液中都显示出强烈的红光发射。
The first observation of luminescence from a structurally well-defined Ag2S molecular nanocluster is reported. Reaction of AgSBut/AgBF4 with N2H4 in methanol affords the tetracationic cluster [Ag62S13(SBut)(32)](BF4)(4), which has a core-shell configuration. The 14 silver(I) centers of the [Ag14S13] core are in a face-centered cubic arrangement with each edge bridged by a S2- ligand; the core is further connected to the [Ag-48(SBut)(32)] shell via both Ag-S bonds and Ag center dot center dot center dot Ag interactions. This novel cluster displays intense red emission in both the solid state and solution at room temperature.
