Al_(20)Cp_8*X_(10) (X = Cl,Br):Snapshots of the Formation of Metalloid Clusters from Polyhedral Al_nX_m Molecules?

摘要

Two subgroups of Al-metal clusters with a predominant number of metal-metal bonds are known:"naked" metal-atom clusters,which are produced from solid metal by laser ablation techniques,and metalloid clusters,which are formed in solution starting with Al~I species and,for example,subsequent reduction.
