[Ag(Sn₉–Sn₉)]⁵⁻ and [(η⁴-Sn₉)Ag(η¹-Sn₉)]⁷⁻, as aggregates of spherical aromatic building blocks. Persistence of aromaticity upon cluster gathering

Abstract

Formation of cluster-based materials requires a fundamental understanding of the resulting cluster aggregation processes. The Sn94- Zintl-ion structure can be viewed as a building block featuring a spherical aromatic species,...
