Abstract

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 (Ph3 P)8 (dpa)6 ] (SbF6 )2 (Hdpa=2, 2′‐dipyridylamine), has a stable pseudo‐ Ih Au32 8+ core with S 6 symmetry, which features an Au12 @Au20 Keplerate cage co‐protected by Ph3 P 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.
