Materials Data on Rb3Rh by Materials Project

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.

Materials Data on Rb3Rh by Materials Project

Rb3Rh is alpha bismuth trifluoride structured and crystallizes in the tetragonal I4/mmm 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 distorted RbRb4Rh4 tetrahedra that share corners with eight equivalent RbRb8Rh4 cuboctahedra, corners with eight equivalent RbRb4Rh4 tetrahedra, edges with four equivalent RbRb8Rh4 cuboctahedra, edges with twelve equivalent RbRb4Rh4 tetrahedra, and faces with six equivalent 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 to eight equivalent Rb and four equivalent Rh atoms to form distorted RbRb8Rh4 cuboctahedra that share corners with four equivalent RbRb8Rh4 cuboctahedra, corners with sixteen equivalent RbRb4Rh4 tetrahedra, edges with eight equivalent RbRb8Rh4 cuboctahedra, edges with eight equivalent RbRb4Rh4 tetrahedra, and faces with four equivalent RbRb8Rh4 cuboctahedra. All Rb–Rh bond lengths are 4.21 Å. Rh is bonded in a distorted body-centered cubic geometry to twelve Rb atoms.
