Phosphorus heptabromide is an inorganic compound with the chemical formula P Br 7.It is one of the phosphorus bromides.At normal conditions, it forms red prismatic crystals. PBr 7 can be prepared by the sublimation of a mixture of phosphorus pentabromide and bromine.
Phosphorus pentabromide is a reactive, yellow solid of formula P Br 5, which has the structure [PBr 4] + Br − (tetrabromophosphonium bromide) in the solid state but in the vapor phase is completely dissociated to PBr 3 and Br 2.

PBr 3 is prepared by treating red phosphorus with bromine. An excess of phosphorus is used in order to prevent formation of PBr 5: [1] [2] P 4 + 6 Br 2 → 4 PBr 3. Because the reaction is highly exothermic, it is often conducted in the presence of a diluent such as PBr 3. Phosphorus tribromide is also generated in situ from red phosphorus and ...
