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.
properties
Thiazyl fluoride is a pungent, colorless gas. It is not thermally stable, very reactive and decomposes on contact with water. It slowly attacks glass even at room temperature. In the liquid phase it trimerizes to (NSF) 3 .
