Uranyl bromide is an compound of uranium, oxygen, and bromine with the chemical formula UO₂Br₂. ^{[1] [2]}

Synthesis

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]

Physical properties

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 ]}
