Chemical compound
Rhenium heptafluoride is the compound with the formula ReF7. It is a yellow low melting solid and is the only thermally stable metal heptafluoride.[2] It has a distorted pentagonal bipyramidal structure similar to IF7, which was confirmed by neutron diffraction at 1.5 K.[3] The structure is non-rigid, as evidenced by electron diffraction studies.[4]
