Rhenium tetrafluoride is a binary inorganic compound of rhenium and fluorine with the chemical formula ReF4.[1]
Synthesis
Rhenium tetrafluoride can be made by the reduction of rhenium hexafluoride with hydrogen, rhenium, or sulfur dioxide:[2][3]
- ReF6 + H2 → 2ReF4 + 2HF
- 2ReF6 + Re → 3ReF4
- ReF6 + SO2 → ReF4 + SO2F2
Physical properties
Rhenium tetrafluoride forms blue crystals[4] of tetragonal structure, cell parameters a = 1.012 nm, c = 1.595 nm.
Rhenium tetrafluoride reacts with water, and corrodes glass when heated.
