Materials Data on Rb3Tc by Materials Project
Rb3Tc is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded to four equivalent Rb1+ and four equivalent Tc3- atoms to form a mixture of corner, edge, and face-sharing RbRb4Tc4 tetrahedra. All Rb–Rb bond lengths are 4.10 Å. All Rb–Tc bond lengths are 4.10 Å. In the second Rb1+ site, Rb1+ is bonded in a distorted body-centered cubic geometry to eight equivalent Rb1+ atoms. Tc3- is bonded in a body-centered cubic geometry to eight equivalent Rb1+ atoms.
