Materials Data on Rb3Tc by Materials Project

Rb3Tc is alpha bismuth trifluoride structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded to four equivalent Tc3- atoms to form a mixture of distorted corner and edge-sharing RbTc4 tetrahedra. All Rb–Tc bond lengths are 4.17 Å. In the second Rb1+ site, Rb1+ is bonded in a square co-planar geometry to four equivalent Tc3- atoms. All Rb–Tc bond lengths are 4.36 Å. Tc3- is bonded to twelve Rb1+ atoms to form a mixture of corner, edge, and face-sharing TcRb12 cuboctahedra.

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.
