Iodine monobromide is an interhalogen compound. It is a dark red solid that melts near room temperature. Like iodine monochloride, IBr is used in some types of iodometry. It serves as a source of I+.

Synthesis[edit]

Iodine monobromide is formed when iodine and bromine are combined:[1]

I2 + Br2 → 2 IBr
