Materials Data on Rb3Th by Materials Project

Abstract

Rb3Th is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Rb is bonded to eight equivalent Rb and four equivalent Th atoms to form distorted RbRb8Th4 cuboctahedra that share corners with twelve equivalent RbRb8Th4 cuboctahedra, edges with eight equivalent ThRb12 cuboctahedra, edges with sixteen equivalent RbRb8Th4 cuboctahedra, faces with four equivalent ThRb12 cuboctahedra, and faces with fourteen equivalent RbRb8Th4 cuboctahedra. All Rb–Rb bond lengths are 4.43 Å. All Rb–Th bond lengths are 4.43 Å. Th is bonded to twelve equivalent Rb atoms to form ThRb12 cuboctahedra that share corners with twelve equivalent ThRb12 cuboctahedra, edges with twenty-four equivalent RbRb8Th4 cuboctahedra, faces with six equivalent ThRb12 cuboctahedra, and faces with twelve equivalent RbRb8Th4 cuboctahedra.
