Rhenium(III) iodide is a binary chemical compound of rhenium and iodide with the chemical formula ReI3.[1][2]
Synthesis
Rhenium(III) iodide can be synthesized by the decomposition of rhenium(IV) iodide:[3][4]
- 2ReI
4 → 2ReI
3 + I
2
- 2ReI
Another way to make it is by introduction of ethanol into a mixture of perrhenic acid and hydroiodic acid.
- HReO
4 + 3HI + 2C
2H
5OH → ReI
3 + 4H
2O + 2CH
3CHO
- HReO
Physical properties
Rhenium(III) iodide forms violet-black crystals. It is poorly soluble in water, acetone, ethanol, ether, and dilute acid solutions.
Chemical properties
When heated in vacuum up to 170 °C, the compound decomposes to rhenium(II) iodide, and at 380 °C — to rhenium(I) iodide:
- 2ReI
3 → 2ReI
2 + I
2 - ReI
3 → ReI + I
2
- 2ReI
