Chemical compound

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

[edit]

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

[edit]

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.
