通过质谱和核磁共振波谱首次观察到氢化物（H-）掺杂到扁圆状金簇[Au-9（PPh3）（8）]（3+）中。产物[Au9H(PPh3)(8)](2+)的密度泛函理论计算表明，(Au9H)(2+)核可以被视为具有封闭电子壳层的近球形超原子。氢化物掺杂超原子 (Au9H)(2+) 成功转化为众所周知的超原子 Au-11(3+)，通过自下而上的方法提供了一种新的原子级精确合成 Au 团簇。
Doping of a hydride (H-) into an oblate-shaped gold cluster [Au-9(PPh3)(8)](3+) was observed for the first time by mass spectrometry and NMR spectroscopy. Density functional theory calculations for the product [Au9H(PPh3)(8)](2+) demonstrated that the (Au9H)(2+) core can be viewed as a nearly spherical superatom with a closed electronic shell. The hydride-doped superatom (Au9H)(2+) was successfully converted to the well-known superatom Au-11(3+), providing a new atomically precise synthesis of Au clusters via a bottom-up approach.
