Titanium(III) fluoride

Titanium(III) fluoride, also known as titanium trifluoride, is an inorganic chemical compound with the formula TiF₃. It is a blue solid that is insoluble in water and most common solvents.

Properties:

Titanium(III) fluoride is a reducing agent. It is paramagnetic due to the presence of unpaired electrons in the Ti³⁺ ion. It sublimes at high temperatures under vacuum. The crystal structure is similar to that of vanadium(III) fluoride and adopts a distorted rhenium trioxide structure.

Synthesis:

Titanium(III) fluoride can be synthesized by the reaction of titanium(III) chloride with anhydrous hydrogen fluoride:

TiCl₃ + 3HF → TiF₃ + 3HCl

It can also be prepared by reducing titanium(IV) fluoride (TiF₄) with titanium metal at high temperatures.

Uses:

While its applications are limited, titanium(III) fluoride finds use in some specialized chemical syntheses and research applications, primarily due to its reducing properties. It's also studied for its magnetic properties and potential uses in materials science.
