Uranium(III) bromide explained

Uranium(III) bromide is an inorganic compound with the chemical formula UBr₃. It is radioactive.

Preparation

Uranium(III) bromide can be obtained by the reaction of uranium metal or uranium(III) hydride and hydrogen bromide,^[1] or it can also be prepared by the thermal decomposition of NH₄UBr₄·1.5CH₃CN·6H₂O. ^[2] It is difficult to synthesize due to its rapid oxidation in both water and air.^[3]
