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

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.
