Materials Data on ReF7 by Materials Project

ReF7 is alpha U structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of two ReF7 clusters. Re7+ is bonded in a pentagonal bipyramidal geometry to seven F1- atoms. There are a spread of Re–F bond distances ranging from 1.85–1.90 Å. There are seven inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Re7+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Re7+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one Re7+ atom. In the fourth F1- site, F1- is bonded in a single-bond geometry to one Re7+ atom. In the fifth F1- site, F1- is bonded in a single-bond geometry to one Re7+ atom. In the sixth F1- site, F1- is bonded in a single-bond geometry to one Re7+ atom. In the seventh F1- site, F1- is bonded in a single-bond geometry to one Re7+ atom.

Materials Data on Re3F by Materials Project

Re3F is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent Re sites. In the first Re site, Re is bonded to four equivalent Re and four equivalent F atoms to form a mixture of edge, face, and corner-sharing ReRe4F4 tetrahedra. All Re–Re bond lengths are 2.64 Å. All Re–F bond lengths are 2.64 Å. In the second Re site, Re is bonded in a body-centered cubic geometry to eight equivalent Re atoms. F is bonded in a body-centered cubic geometry to eight equivalent Re atoms.
