| Abstract: | The preparation of protonated methanesulfonamide was carried out using the superacidic systems HF/AsF5 and HF/SbF5. The vibrational spectroscopic characterization was supported by quantum chemical calculations performed with the PBE1PBE method using the 6‐311G++(3df, 3pd) basis set. A remarkable long nitrogen–sulfur bond length of 1.804(6) Å was observed in a single‐crystal X‐ray structure analysis of [CH3SO2NH3]+[Sb2F11]–. It crystallizes in the orthorhombic space group P21/c with four formula units in the unit cell. Furthermore the crystal structure of CH3SO2NH2 was revisited. |
