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.[1] It adopts a defect perovskite-like structure such that each Ti center has octahedral coordination geometry, and each fluoride ligand is doubly bridging.[2]
