Carboxylic acid stimulated silver shell isomerism in a triple core-shell Ag₈₄ nanocluster.

ABSTRACT: Isomerization is highly important in all aspects of science, yet it is rarely observed in nanoscience. Here, we synthesized a unique triple core-shell Ag₈₄ nanocluster displaying isomerism, which is controlled by different carboxylic acids and a one-way transformation (SD/Ag84a → SD/Ag84b). The innermost core is a rare Ag₁₀ nanocluster which comprises an Ag₆ octahedral unit as seen in face-centred cubic (fcc) silver metal and four capped Ag atoms. It templates two crescent-shaped polyoxometalate (W₇O₂₆)^10- shells which are then enclosed in a shell of silver shaped as rugby balls. The organic ligands (ⁱPrS^-, ⁿ PrCOO^- and PhCOO^-) finally shield the met
