Materials Data on Rb3Sn by Materials Project
Rb3Sn is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. there are two inequivalent Rb sites. In the first Rb site, Rb is bonded to four equivalent Rb and four equivalent Sn atoms to form a mixture of distorted edge, corner, and face-sharing RbRb4Sn4 tetrahedra. All Rb–Rb bond lengths are 4.03 Å. All Rb–Sn bond lengths are 4.03 Å. In the second Rb site, Rb is bonded in a body-centered cubic geometry to eight equivalent Rb atoms. Sn is bonded in a body-centered cubic geometry to eight equivalent Rb atoms.
