A Ligand‐Protected Golden Fullerene: The Dipyridylamido Au328+ Nanocluster
Authors:Shang‐Fu Yuan  Cong‐Qiao Xu  Jun Li  Quan‐Ming Wang
Abstract:A golden fullerene Au32 cluster has been synthesized with amido and phosphine ligands as the protecting agents. Single‐crystal X‐ray structural analysis revealed that this gold nanocluster, Au32(Ph3P)8(dpa)6] (SbF6)2 (Hdpa=2,2′‐dipyridylamine), has a stable pseudo‐Ih Au328+ core with S6 symmetry, which features an Au12@Au20 Keplerate cage co‐protected by Ph3P and dpa ligands. Quantum‐chemical studies were conducted to elucidate the origin of the special stability of this cluster, and suggest that it is electronically stabilized through metal–ligand interactions.
Keywords:Amido-Liganden  Clusterverbindungen  Gold  Optische Eigenschaften  Nanocluster
