Diphosphine-protected ultrasmall gold nanoclusters: opened icosahedral Au₁₃ and heart-shaped Au₈ clusters.

ABSTRACT: Due to distinctive quantum confinement effects, ultrasmall gold nanoparticles usually exhibit interesting electronic structure and molecular-like properties. However, the lack of atomically-precise structural information makes the understanding of them almost impossible, such as understanding the relationships between their compositions and unique properties. Herein, by reducing a diphosphine Au^I precursor (Au₂(dppm)₂Cl₂; dppm = Ph₂PCH₂PPh₂) with or without a S^2- releasing reagent, we enriched our knowledge of the members in the families of Au₁₃ and Au₈ by the structural determinations of two new dppm-protected gold nanoclusters, [Au₁₃(dppm)₆]⁵⁺ (
