Titanium(III) fluoride is the inorganic compound with the formula TiF3. A violet, paramagnetic solid, it is one of two titanium fluorides, the other being titanium tetrafluoride.[3] It adopts a defect perovskite-like structure such that each Ti center has octahedral coordination geometry, and each fluoride ligand is doubly bridging.[4]

Titanium(III) fluoride can be prepared by dissolution of titanium metal in hydrofluoric acid. It oxidizes to Titanium dioxide (TiO2) above 100 °C (212 °F) in air.[3]
