Rhenium pentafluoride is a binary inorganic compound of rhenium and fluorine with the chemical formula ReF5.[1] This is a salt of rhenium and hydrofluoric acid.[2]
Synthesis
Rhenium pentafluoride can be synthesised by the reduction of rhenium hexafluoride with hydrogen, rhenium, or tungsten:
- 2ReF6 + H2 → 2ReF5 + 2HF
- 5ReF6 + Re → 6ReF5
- 6ReF6 + W → 6ReF5 + WF6
Physical properties
Rhenium pentafluoride forms yellow-green crystals[3] of orthorhombic crystal system, cell parameters a = 0.57 nm, b = 1.723 nm, c = 0.767 nm.
Rhenium pentafluoride reacts with water.
Rhenium pentafluoride is volatile. The compound consists of dimers of composition Re2F10.
