Titanium(III) bromide is the inorganic compound with the formula TiBr3. It is a blue black solid with a reddish reflection. It has few applications although it is a catalyst for the production of polymerization of alkenes.
Production and structure
TiBr3 can be produced by heating the tetrabromide under hydrogen gas:[3]
- 2 TiBr4 + H2 → 2 TiBr3 + 2 HBr
It can also be produced by comproportionation of titanium metal and titanium tetrabromide.[4]
- Ti + 3 TiBr4 → TiBr3
There are two polymorph]]s, each adopting a layered structure typical of metal trihalides.[4]
Reactions
Heating the tribromide gives the dibromide together with the volatile tetrabromide:[3]
- TiBr3 → 2 TiBr4 + TiBr2
The solid dissolves in donor solvents such as pyridine and nitriles to produce 3:1 adducts:
- TiBr3 + 3 L → 2 TiBr3L3
