Synthesis

edit

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

edit

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.
