Hafnium tetrabromide is the inorganic compound with the formula HfBr₄. It is the most common bromide of hafnium. It is a colorless, diamagnetic moisture sensitive solid that sublimes in vacuum.W. Thomas, H. Elias "Darstellung von HfCl₄ und HfBr₄ durch Umsetzung von Hafnium mit Geschmolzenen Metallhalogeniden" Journal of Inorganic and Nuclear Chemistry 1976, Volume 38, Pages 2227–2229. {{doi|10.1016/0022-1902(76)80199-6}} It adopts a structure very similar to that of zirconium tetrabromide, featuring tetrahedral Hf centers, in contrast to the polymeric nature of hafnium tetrachloride.Berdonosov, S. S.; Berdonosova, D. G.; Lapitskii, A. V.; Vlasov, L. G. "X-ray study of hafnium tetrabromide" Zhurnal Neorganicheskoi Khimii, 1963, vol. 8, 531-2.
