Titanium(III) fluoride is the inorganic compound with the formula Ti F3. 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]

Titanium(III) fluoride can be prepared by dissolution of titanium metal in hydrogen fluoride. [1]

Dysprosium(II) chloride (DyCl2), also known as dysprosium dichloride, is an ionic chemical compound of dysprosium and chlorine. This salt is a reduced compound, as the normal oxidation state of dysprosium in dysprosium compounds is +3.

The +4 oxidation state dominates titanium chemistry, but compounds in the +3 oxidation state are also numerous. Commonly, titanium adopts an octahedral coordination geometry in its complexes, but tetrahedral TiCl4 is a notable exception. Because of its high oxidation state, titanium(IV) compounds exhibit a high degree of covalent bonding.
