Titanium(III) bromide is the inorganic compound with the formula TiBr3. It is a blue black paramagnetic solid with a reddish reflection. It has few applications, although it is a catalyst for the polymerization of alkenes.

Production and structure
TiBr3 can be produced by heating the tetrabromide in an atmosphere of hydrogen:
2 TiBr4 + H2 → 2 TiBr3 + 2 HBrIt can also be produced by comproportionation of titanium metal and titanium tetrabromide.
Ti + 3 TiBr4 → 4 TiBr3There are two polymorphs, each exhibiting octahedral Ti centers.
Reactions
Heating the tribromide gives the dibromide together with the volatile tetrabromide:
TiBr3 → 2 TiBr4 + TiBr2The solid dissolves in donor solvents (L) such as pyridine and nitriles to produce 3:1 adducts:
TiBr3 + 3 L → 2 TiBr3L3References
