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]
