Thiazyl trifluoride is a chemical compound of nitrogen, sulfur, and fluorine, having the formula NSF3. It exists as a stable, colourless gas, and is an important precursor to other sulfur-nitrogen-fluorine compounds.[1] It has tetrahedral molecular geometry around the sulfur atom, and is regarded to be a prime example of a compound that has a sulfur-nitrogen triple bond.[2]

NSF3 can be synthesised by the fluorination of thiazyl fluoride, NSF, with silver(II) fluoride, AgF2:

NSF + 2 AgF2 → NSF3 + 2 AgF

It is also a product of the oxidation of ammonia by S2F10.[3]
