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 of trifluorosulfonium tetrafluoroborate [SF₃]⁺[BF₄]⁻ 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]}
