Rhenium(III) iodide is a binary chemical compound of
rhenium and
iodide with the chemical formula ReI
3.

Rhenium(III) iodide can be synthesized by the decomposition of rhenium(IV) iodide: [3] [4]
Another way to make it is by introduction of ethanol into a mixture of perrhenic acid and hydroiodic acid.
Rhenium(III) iodide forms violet-black crystals. It is poorly soluble in water, acetone, ethanol, ether, and dilute acid solutions.
When heated in vacuum up to 170 °C, the compound decomposes to rhenium(II) iodide, and at 380 °C — to rhenium(I) iodide:
