A golden fullerene Au 32 cluster has been synthesized with amido and phosphine ligands as the protecting agents. Single‐crystal X‐ray structural analysis revealed that this gold nanocluster, [Au 32 (Ph 3 P) 8 (dpa) 6 ] (SbF 6 ) 2 (Hdpa=2,2′‐dipyridylamine), has a stable pseudo‐ I h Au 32 8+ core with S 6 symmetry, which features an Au 12 @Au 20 Keplerate cage co‐protected by Ph 3 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.
