Nitronium fluorosulfonate , NO ₂ SO ₃ F is an inorganic compound of the nitronium ion NO ₂⁺ with the fluorosulfonic acid HSO ₃ F.

Extraction and presentation

The reaction of nitrogen dioxide and peroxydisulfuryl difluoride allows the salt to be synthesized.

The monoclinic crystal system can be found in the crystal structure of nitronium fluorosulfonate. With the space group C 2 / c (space group no. 15) it has the lattice parameters a = 9.275 ± 0.004 Å , b = 7 ± 0.012 Å and c = 7.36 ± 0.008 Å. The angular degree of β is 113.8 °. Template: room group / 15

Upon contact with water , the salt decomposes into nitric acid and fluorosulfonic acid .
