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
