Sn368-: a 2.7 nm naked aromatic tin rod

In this work, we synthesize naked tin cluster anion Sn-36(8-), representing the first example of pure Sn nanowire assembled through oxidative coupling reactions of a super atomic cluster Sn-9(4-). Theoretical analysis confirm the presence of aromaticity for each Sn-9 unit showing four adjacent aromatic subunits bridged by parallel Sn-Sn bonds.
