Au₃₀(PⁱPr₂ⁿBu)₁₂Cl₆-An Open Cluster Provides Insight into the Influence of the Sterical Demand of the Phosphine Ligand in the Formation of Metalloid Gold Clusters.

ABSTRACT: Phosphine-stabilized gold clusters are an important subgroup of metalloid gold cluster compounds and are important model compounds for nanoparticles. Although there are numerous gold clusters with different phosphine ligands, the effect of phosphine on cluster formation and structure remains unclear. While the linear alkyl-substituted phosphine gold chlorides result in a Au₃₂ cluster, the bulky ^tBu₃P leads to a Au₂₀ cluster. The reduction of (ⁱPr₂ⁿBuP)AuCl, with the steric demand of the phosphine ligand between the mentioned phosphines, results in the successful synthesis and crystallization of a new metalloid gold cluster, Au₃₀(PⁱPr₂ⁿB
