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]
