Chemical compound

Rhenium tetrafluoride is a binary inorganic compound of rhenium and fluorine with the chemical formula ReF4.

Synthesis

Rhenium tetrafluoride can be made by the reduction of rhenium hexafluoride with hydrogen, rhenium, or sulfur dioxide:

ReF6 + H2 → 2ReF4 + 2HF
2ReF6 + Re → 3ReF4
ReF6 + SO2 → ReF4 + SO2F2

Physical properties

Rhenium tetrafluoride forms blue crystals of tetragonal structure, cell parameters a = 1.012 nm, c = 1.595 nm.

Rhenium tetrafluoride reacts with water, and corrodes glass when heated.
