Titanium(III) bromide is theinorganic 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 thepolymerization of alkenes.
TiBr3 can be produced by heating the tetrabromide in an atmosphere ofhydrogen:[3]
It can also be produced bycomproportionation of titanium metal andtitanium tetrabromide.[4][5]
Twopolymorphs of TiBr3 are known, each exhibiting octahedral Ti centers.[4]
Heating the tribromide givestitanium(II) bromide together with the volatile tetrabromide:[3]
The solid dissolves in donor solvents (L) such as pyridine and nitriles to produce 3:1 adducts:
