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.
Like polonium tetraiodide, polonium tetrabromide can also be produced by the reaction of polonium dioxide and hydrogen bromide:
- PoO2 + 4 HBr → PoBr4 + 2 H2O
Properties
Polonium tetrabromide is a light red solid that is easily deliquescent. It crystallizes in the cubic crystal system, with space group Fm3m (No. 225) and lattice parameter a = 5.6 Å.
