HCl‐Induced Nuclearity Convergence in Diphosphine‐Protected Ultrasmall Gold Clusters: A Novel Synthetic Route to “Magic‐Number” Au13 Clusters

A magic-number Au13 cluster with icosahedral geometry can be exclusively generated from a polydisperse mixture of ultrasmall 1,2-bis(diphenylphosphino)ethane-coordinated gold clusters upon treatment with HCl, which acts as an efficient promoter.
