Abstract

In this work, we synthesize naked tin cluster anion Sn₃₆^8-, representing the first example of pure Sn nanowire assembled through oxidative coupling reactions of a super atomic cluster Sn₉^4-. Theoretical analysis confirm the presence of aromaticity for each Sn₉ unit showing four adjacent aromatic subunits bridged by parallel Sn-Sn bonds.
