Polonium tetrabromide, is a bromide of polonium, with the chemical formula PoBr₄.

Preparation

Polonium tetrabromide can be formed by the direct reaction of bromine and polonium at 200 °C to 250 °C.^[2]

Like polonium tetraiodide, polonium tetrabromide can also be produced by the reaction of polonium dioxide and hydrogen bromide:^[2]

PoO₂ + 4 HBr → PoBr₄ + 2 H₂O

Polonium tetrabromide is a light red solid that is easily deliquescent.^[1] It crystallizes in the cubic crystal system, with space group Fm3m (No. 225) and lattice parameter a = 5.6 Å.^[3]
