Tailoring the subshell and electronic structure of an atomically precise AuAg alloy nanocluster

Abstract

Manipulating the atomic-level structure of the subshell of a nanocluster while preserving the inner and outer shell structure is challenging. We present the synthesis and molecular structure of an alkynyl-protected Au₃₄Ag₂₇ nanocluster, which exhibits distinct third shell atomic arrangement, electronic structure, and optical properties from those of the Au₃₄Ag₂₈ nanocluster.
