Zirconium(IV) bromide

Zirconium(IV) bromide is the chemical compound with the formula ZrBr4. This colorless solid is the principal precursor to other Zr-Br compounds. It is prepared by the action of bromine on Zr powder and purified by sublimation.

Its structure is polymeric with octahedral ZrBr6 centers. The structure can also be described as cubic close-packed, with 1/4th of the octahedral holes filled.

In the gas phase, ZrBr4 is tetrahedral.

Like related tetrahalides of Ti and Hf, ZrBr4 hydrolyzes in air to give oxy-halides, with release of hydrogen bromide
