Ag₁₀Cu₁₆ nanoclusters with triple-ligand protection: total structure and electronic structure analysis

Abstract

Illustrating molecualr strucure of metal nanoclusters with the protection of multiple ligands is the prequisite to understand strucure-property relationships of nano or bulk materials with hybrid interfaces. Reported herein is...

Atom-Precise Ligated Copper and Copper-Rich Nanoclusters with Mixed-Valent Cu(I)/Cu(0) Character: Structure–Electron Count Relationships

“…Its 4 silver atoms form a central [Ag4] 2+ tetrahedron, whereas the 15 copper atoms surround this superatomic core as Cu(I) centers [65]. A similar situation has been shown to exist in 27, where the superatomic core has been identified as a [Ag6] 4+ octahedron [66], thus leaving the four remaining Ag atoms and all the Cu atoms in the +I oxidation state. On the other hand, there seem to be two The clusters of type 26 are isoelectronic and isostructural to their homometallic counterpart 7 [64], with gold at the center, as expected.…”
