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.
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 monochloride (BrCl) is a yellow-brown gas with a boiling point of 5 °C. Iodine monochloride (ICl) exists as red transparent crystals that melt at 27.2 °C to form a choking brownish liquid (similar in appearance and weight to bromine). It reacts with HCl to form the strong acid HICl 2.
Bromine fluoride may refer to several compounds with the elements bromine and fluorine: Bromine monofluoride, BrF; Bromine trifluoride, BrF 3; Bromine pentafluoride ...
Bromine monofluoride is a quite unstable interhalogen compound with the chemical formula BrF. It can be produced through the reaction of bromine trifluoride (or bromine pentafluoride) and bromine. Due to its lability, the compound can be detected but not isolated: [2] BrF 3 + Br 2 → 3 BrF BrF 5 + 2 Br 2 → 5 BrF Br 2(l) + F 2(g) → 2 BrF (g)

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]
Upon treatment with fluorine, it converts to iodine heptafluoride: [6] IF 5 + F 2 → IF 7. It has been used as a solvent for handling metal fluorides. For example, the reduction of osmium hexafluoride to osmium pentafluoride with iodine is conducted in a solution in iodine pentafluoride: [7] 10 OsF 6 + I 2 → 10 OsF 5 + 2 IF 5
