Production and structure
TiBr3 can be produced by heating the tetrabromide in an atmosphere of hydrogen:[3]
- 2 TiBr4 + H2 → 2 TiBr3 + 2 HBr
It can also be produced by comproportionation of titanium metal and titanium tetrabromide.[4][5]
- Ti + 3 TiBr4 → 4 TiBr3
Two polymorphs of TiBr3 are known, each exhibiting octahedral Ti centers.[4]
Reactions
Heating the tribromide gives titanium(II) bromide together with the volatile tetrabromide:[3]
- 2 TiBr3 → TiBr4 + TiBr2
The solid dissolves in donor solvents (L) such as pyridine and nitriles to produce 3:1 adducts:
- TiBr3 + 3 L → TiBr3L3
