Iodine monobromide is an interhalogen compound with the formula IBr. It is a dark red solid that melts near room temperature.^[1] Like iodine monochloride, 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 I₂ in the ECW model. It can form CT adducts with Lewis donors.^[2]

Iodine monobromide is formed when iodine and bromine are combined in a chemical reaction:.^[3]

I₂ + Br₂ → 2 IBr
