Rhenium heptafluoride GudangMovies21 Rebahinxxi LK21

Rhenium heptafluoride is the compound with the formula ReF7. It is a yellow low melting solid and is the only thermally stable metal heptafluoride. It has a distorted pentagonal bipyramidal structure similar to IF7, which was confirmed by neutron diffraction at 1.5 K. The structure is non-rigid, as evidenced by electron diffraction studies.




Production, reactions and properties


Rhenium heptafluoride can be prepared from the elements at 400 °C:

2 Re + 7 F2 → 2 ReF7
It also can be produced by the explosion of rhenium metal under sulfur hexafluoride.
It hydrolyzes under a base to form perrhenic acid and hydrogen fluoride:

ReF7 + 4H2O → HReO4 + 7HF
With fluoride donors such as CsF, the ReF−8 anion is formed, which has a square antiprismatic structure. With antimony pentafluoride, SbF5, a fluoride acceptor, the ReF+6 cation is formed.
