Materials Data on Ta3Re by Materials Project
Ta3Re is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent Ta sites. In the first Ta site, Ta is bonded to four equivalent Ta and four equivalent Re atoms to form a mixture of distorted corner, edge, and face-sharing TaTa4Re4 tetrahedra. All Ta–Ta bond lengths are 2.82 Å. All Ta–Re bond lengths are 2.82 Å. In the second Ta site, Ta is bonded in a 8-coordinate geometry to eight equivalent Ta and six equivalent Re atoms. All Ta–Re bond lengths are 3.25 Å. Re is bonded in a distorted body-centered cubic geometry to fourteen Ta atoms.
