A golden fullerene Au 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 (Ph P) (dpa) ] (SbF ) (Hdpa=2,2'-dipyridylamine), has a stable pseudo-I Au core with S symmetry, which features an Au @Au Keplerate cage co-protected by Ph 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.
以酰胺和膦配体作为保护剂合成了一种金色的富勒烯金簇。单晶X射线结构分析表明，这种金纳米簇Au(PhP)(dpa)(Hdpa = 2,2'-联吡啶胺)具有一个具有S对称性的稳定的准I型Au核，其特征是由PhP和dpa配体共同保护的Au@Au开普勒笼。进行了量子化学研究以阐明该簇特殊稳定性的起源，并表明它通过金属-配体相互作用在电子上得到稳定。
