Nitrosonium hexafluoroantimonate is an inorganic compound with the chemical formula NOF6Sb, composed of the nitrosonium cation [NO]+ and hexafluoroantimonate anion [SbF6]-. The decomposition of this substance releases hydrogen fluoride, nitrogen oxides, and antimony oxides.
Uses Nitrosonium hexafluoroantimonate is used as an oxidizing agent in organic synthesis.
Reactions Nitrosonium hexafluoroantimonate forms mixed-cation salts with other hexafluoroantimonates in liquid anhydrous hydrogen fluoride. For example:
NOSbF6 + Cu(SbF6)2 → NOCu(SbF6)3
