Zirconium Oxybromides

Zirconium Oxybromides resemble the oxychlorides. By the evaporation over sulphuric acid of an aqueous solution of the tetrabromide crystals of ZrOBr₂.8H₂O are formed, and when these are heated to 100° - 120° C. in a current of hydrogen bromide ZrOBr₂.4H₂O results; whilst from a solution of titanium hydroxide in hydrobromic acid the compounds Zr(OH)₃Br.2H₂O and Zr(OH)₃Br.H₂O can be obtained.
