Materials Data on Rb3Rh by Materials Project

Abstract

Rb3Rh 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 Rh atoms to form a mixture of distorted edge, face, and corner-sharing RbRb4Rh4 tetrahedra. All Rb–Rb bond lengths are 3.70 Å. All Rb–Rh bond lengths are 3.70 Å. In the second Rb site, Rb is bonded in a 8-coordinate geometry to eight equivalent Rb and six equivalent Rh atoms. All Rb–Rh bond lengths are 4.27 Å. Rh is bonded in a body-centered cubic geometry to fourteen Rb atoms.
