The only binary heptafluorides are iodine heptafluoride (IF 7), rhenium heptafluoride (ReF 7), and gold heptafluoride (AuF 7).Only IF 7 and ReF 7 are true heptafluorides, however, as AuF 7 is actually a coordination complex of gold pentafluoride (AuF 5) and molecular fluorine; therefore, the correct chemical formula of gold heptafluoride is actually AuF 5 ·F 2.

Bromine pentafluoride (BrF 5) is a colourless fuming liquid, made by reacting bromine trifluoride with fluorine at 200 °C. It is physically stable, but decomposes violently on contact with water, organic substances, and most metals and nonmetals .
The Platinum Metals and their Alloys. New York: The International Nickel Company, Inc., 1941: 16. — "Values ranging from 21.3 to 21.5 gm/cm 3 at 20 °C have been reported for the density of annealed platinum; the best value being about 21.45 gm/cm 3 at 20 °C." 21.46 g/cm 3 — Rose, T.

Industrially, it is mainly produced by the reaction of hydrogen gas with bromine gas at 200–400 °C with a platinum catalyst. However, reduction of bromine with red phosphorus is a more practical way to produce hydrogen bromide in the laboratory: [2] 2 P + 6 H 2 O + 3 Br 2 → 6 HBr + 2 H 3 PO 3 H 3 PO 3 + H 2 O + Br 2 → 2 HBr + H 3 PO 4
The well-characterized heavier halogens (chlorine, bromine, and iodine) all form mono-, tri-, and pentafluorides: XF, XF 3, and XF 5. Of the neutral +7 species, only iodine heptafluoride is known. [93] While chlorine and bromine heptafluorides are not known, the corresponding cations ClF + 6 and BrF + 6, extremely strong oxidizers, are. [94]
Bromine pentafluoride, Br F 5, is an interhalogen compound and a fluoride of bromine.It is a strong fluorinating agent.. BrF 5 finds use in oxygen isotope analysis. Laser ablation of solid silicates in the presence of BrF 5 releases O 2 for subsequent analysis. [2]
