Trapping an octahedral Ag6 kernel in a seven-fold symmetric Ag56 nanowheel

Abstract

High-nuclearity silver clusters are appealing synthetic targets for their remarkable structures, but most are isolated serendipitously. Here, the authors describe the rational use of solvents to form cluster-in-cluster silver nanowheels, which comprise an octahedral Ag6 4+ core surrounded by a Ag56 cage of unusual seven-fold symmetry.
