High-nuclearity clusters resemble the closest model between the determination of atomically precise chemical species and the bulk metallic version thereof, and both impacts on a variety of applications, including catalysis, optics, sensors, and new energy sources. Our interest lies with the nanoclusters of the Group 11 (Cu, Ag, Au) metals stabilized by dichalcogenido and hydrido ligands. Herein, we describe superatoms formed by the clusters and their relationship with precursor hydrido clusters. Specifically, our concept seeks to demonstrate a possible correlation that exist between hydrido clusters (and nanoalloys) and the formation of superatoms, with the loss of hydrides and typically with release of H gas. These reactions appear to be internal self-redox reactions and require no additional reducing agent, but does seem to require a similar core structure. Knowledge of such processes could provide insight into how clusters grow and an understanding in bridging the atomically precise cluster - metal nanoparticle mechanism.
高核簇类似于在确定原子精确的化学物种及其块状金属形式之间最接近的模型，并且对包括催化、光学、传感器和新能源在内的各种应用都有影响。我们感兴趣的是由二硫属化物和氢化物配体稳定的第11族（铜、银、金）金属的纳米簇。在此，我们描述了由这些簇形成的超原子及其与前体氢化物簇的关系。具体而言，我们的概念旨在证明氢化物簇（和纳米合金）与超原子形成之间可能存在的相关性，伴随着氢化物的损失以及通常氢气的释放。这些反应似乎是内部自氧化还原反应，不需要额外的还原剂，但似乎确实需要类似的核心结构。了解此类过程可以深入了解簇如何生长，并有助于理解原子精确簇与金属纳米颗粒机制之间的联系。
