Sulfur trifluoride is the inorganic chemical compound with the formula SF3. It is a radical.[1][2]

Structure and synthesis

Sulfur trifluoride is predicted to be pyramidal.[3][4]

SF3 is generated by irradiation of crystals SF+
3BF−
4 with gamma rays.[1]

SF−
3

A derivative formally derived from SF−
3 is the coordination complex Ir(Cl)(CO)(F)(SF3)(Et3P)2 obtained by oxidative addition of sulfur tetrafluoride to Ir(Cl)(CO)(PEt3)2 (Et = C2H5).[5][6]
