Nitronium hexafluoroantimonate is an inorganic compound with the chemical formula NO
2F
6Sb, composed of the nitronium cation [NO2]+ and hexafluoroantimonate anion [SbF6]-. It is stable at room temperature under anhydrous conditions.[3] The decomposition of this substance releases hydrogen fluoride, nitrogen oxides, and antimony oxides.
Preparation
Nitronium hexafluoroantimonate can be prepared by reacting dinitrogen tetroxide with antimony trioxide in the presence of bromine trifluoride.[4]
It is also formed by reacting antimony pentafluoride with nitryl fluoride.[5]
Uses
Nitronium hexafluoroantimonate can be used in aromatic nitration reactions.[6]
It can also be used as a P-type dopant on single-walled carbon nanotubes.[7]
