Iodine monobromide is an
interhalogen compound
In chemistry, an interhalogen compound is a molecule which contains two or more different halogen atoms ( fluorine, chlorine, bromine, iodine, or astatine) and no atoms of elements from any other group.

with the chemical symbol IBr. It is a dark red solid that melts near room temperature. Like
iodine monochloride
Iodine monochloride is an interhalogen compound with the formula . It is a red-brown chemical compound that melts near room temperature. Because of the difference in the electronegativity of iodine and chlorine, this molecule is highly polar an ...
, IBr is used in some types of
iodometry. It serves as a source of I
+. Its Lewis acid properties are compared with those of ICl and I
2 in the
ECW model. It can form
CT adducts with Lewis donors.
