Rhenium tetraiodide is a binary chemical compound of rhenium and iodide with the chemical formula ReI
4.[1][2][3]
Synthesis
[edit]Rhenium tetraiodide can be obtained via the reduction of perrhenic acid with hydrogen iodide:[4]
- 2HReO4 + 14HI4 → 2ReI4 + 3I2 + 8H2O
Physical properties
[edit]Rhenium tetraiodide forms black solid substance which is soluble in acetone and ether. Hydrolyzed by water, hygroscopic.[5]
Chemical properties
[edit]Rhenium tetraiodide is hydrolyzed by water:[5]
- ReI4 + 2H2O → ReO2 + 4HI
Rhenium tetraiodide decomposes when heated:[5][6]
- ReI4 → ReI3, ReI2, ReI, I2
