A golden fullerene with a composition of [Au42(Ph3P)10(5‐CF3‐Hpa)8] (CF3COO)2 (5‐CF3‐H2pa = 5‐trifluoropyridyl‐2‐amine) ( Au42 ) has been synthesized with pyridylamino and phosphine ligands as the protecting agents. Single crystal X‐ray structural analysis reveals that the cluster has a D3h Au4210+ core, which can be depicted as a centered core‐shell structure Au@Au15@Au26. The 41 Au atoms of the Au15@Au26 core‐shell can be derived from placing a gold atom in the center of each polygon of C78 (D3h). Surprisingly, the centered gold atom of this noble cluster has the highest coordination number in metal nanoclusters of 15. Quantum‐chemical studies suggest that the excellent stability of Au42 results from both the superatomic characteristics of the Au42 kernel and the gold‐ligand interactions.

配体保护的金富勒烯 Au42,具有前所未有的 15 金属配位数



以吡啶氨基和膦配体为保护剂,合成了组成为 [Au42(Ph3P)10(5-CF3-Hpa)8] (CF3COO)2 (5-CF3-H2pa = 5-三氟吡啶-2-胺) (Au42) 的金富勒烯。单晶 X 射线结构分析显示,该团簇具有 D3h Au4210+ 核心,可以描述为中心核壳结构Au@Au15@Au26。Au15@Au26核壳的 41 个 Au 原子可以通过在 C78 (D3h) 的每个多边形的中心放置一个金原子来得出。令人惊讶的是,这个贵金属团簇的中心金原子在金属纳米团簇中具有最高的配位数,为 15。量子化学研究表明,Au42 的出色稳定性是 Au42 内核的超原子特性和金-配体相互作用的结果。
