Surprisingly stable is the first example of a binary six π electron aromatic SN cation with an N 3 unit, S 2 N 3 + (see picture). It can be isolated on a macroscopic scale when a large counter anion is present. The structure determined by X‐ray investigations is in good agreement with theoretical data. The unequivocal identification was supported by Raman and infrared studies. The structure and bonding are discussed on the basis of MO (molecular orbital) and AIM (atoms‐in‐molecules) analysis.
