Polyoxovanadates (POVs) as templates are still scarcely observed in silver clusters. Herein, the largest known POV-based silver cluster (Ag50) was synthesized, which is a core-shell conformation composed of the generated classical [VO] core and Ag shell, constrained by the S- and O-donor ligands with a specific distribution. Such {VO@Ag} structure displays geometric inheritance from the symmetric decavanadate to the silver skeleton. The solution behavior, solid-state stability and photoelectric properties are discussed in detail. This work provides enlightenment for the further construction of POV-templated high-nuclearity silver clusters.
多氧钒酸盐（POV）作为模板在银簇中仍然很少被观察到。在此，合成了已知最大的基于POV的银簇（Ag50），它是一种核壳结构，由生成的经典[VO]核和Ag壳组成，受具有特定分布的S供体和O供体配体约束。这种{VO@Ag}结构显示出从对称十钒酸盐到银骨架的几何继承性。详细讨论了其溶液行为、固态稳定性和光电性质。这项工作为进一步构建以POV为模板的高核银簇提供了启示。
