Uranyl bromide is an compound of uranium, oxygen, and bromine with the chemical formula UO2Br2. [1] [2]
Uranyl bromide can be obtained by passing bromine vapor over a heated mixture of UO2 and charcoal. The formed compound is extracted with ether. [3]
The compound is highly soluble and hygroscopic, forming intensely red solutions in water. [4] [5] Uranyl bromide is known to form complex compounds with oxygen-containing organic solvents and can undergo reduction to a black powder upon heating in such solutions.[ citation needed ]
