Gold chemistry and the synthesis of colloidal gold have always caught the attention of scientists. While Faraday was investigating the physical properties of colloidal gold in 1857 without probably knowing anything about the exact structure of the molecules, 150 years later the working group of Kornberg synthesized the first structurally characterized multi-shell metalloid gold cluster with more than 100 Au atoms, Au(SR). After this ground-breaking result, many smaller and bigger metalloid gold clusters have been discovered to gain a better understanding of the formation process and the physical properties. In this review, first of all, a general overview of past investigations is given, leading to metalloid gold clusters with staple motifs in the ligand shell, highlighting structural differences in the cores of these clusters. Afterwards, the influence of the synthetic procedure on the outcome of the reactions is discussed, focusing on recent results from our group. Thereby, newly found structural motifs are taken into account and compared to the existing ones. Finally, a short outlook on possible subsequent reactions of these metalloid gold clusters is given.
金化学与胶体金的合成一直吸引着科学家们的关注。1857年，法拉第在研究胶体金的物理性质时，可能对分子的确切结构一无所知。150年后，科恩伯格的研究小组合成了首个结构特征明确的、含有100多个金原子的多壳层类金属金簇Au(SR)。取得这一开创性成果后，人们发现了许多大小各异的类金属金簇，以便更好地理解其形成过程和物理性质。在这篇综述中，首先对过去的研究进行了总体概述，这些研究产生了在配体壳层中具有订书钉基序的类金属金簇，突出了这些簇核心结构上的差异。之后，讨论了合成方法对反应结果的影响，重点是我们小组的最新研究成果。由此，考虑了新发现的结构基序，并与现有的结构基序进行了比较。最后，对这些类金属金簇可能的后续反应给出了简要展望。
