Xenon dibromide is an unstable chemical compound with the chemical formula XeBr₂. It was only produced by the decomposition of iodine-129:[2]

¹²⁹IBr₂^– → XeBr₂ + e^–

Attempts to prepare this compound by combining elemental xenon and bromine only resulted in the XeBr radical.[3] This compound is expected to be less stable than xenon difluoride and xenon dichloride. It is also expected to decompose to xenon and bromine.[1]
