Thiazyl fluoride is an inorganic chemical compound from the group of fluorides .

Extraction and presentation

Thiazyl fluoride can be obtained by reacting nitrogen trifluoride with sulfur at 400 ° C, whereby thiothionyl fluoride is also formed.

It can also be achieved by fluorination of tetrasulfur tetranitride with iodine pentafluoride , sulfur tetrafluoride , selenium hexafluoride , cobalt (III) fluoride , etc., by thermolysis of the mercury compound Hg (NSF 2 ) 2

or obtained by ammonolysis of sulfur tetrafluoride.
