Synthesis
Uranyl iodide can be obtained by treating UO2(OTf)2 with pure Me3SiI,[4]reducing uranyl iodate with aqueous sulfur dioxide, the decomposition of uranyl sulfate with barium or calcium iodide,[5] or adding barium iodide in excess to an ether solution of uranyl nitrate.[1]
Chemical properties
The compound reacts with water and oxygen to produce uranyl hydroxide:[6]
- UO2I2 + H2O + 1/2O2 → UO2(OH)2 + I2
