Materials Data on RbU3 by Materials Project

Abstract

RbU3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Rb is bonded to twelve equivalent U atoms to form RbU12 cuboctahedra that share corners with twelve equivalent RbU12 cuboctahedra, edges with twenty-four equivalent URb4U8 cuboctahedra, faces with six equivalent RbU12 cuboctahedra, and faces with twelve equivalent URb4U8 cuboctahedra. All Rb–U bond lengths are 3.23 Å. U is bonded to four equivalent Rb and eight equivalent U atoms to form distorted URb4U8 cuboctahedra that share corners with twelve equivalent URb4U8 cuboctahedra, edges with eight equivalent RbU12 cuboctahedra, edges with sixteen equivalent URb4U8 cuboctahedra, faces with four equivalent RbU12 cuboctahedra, and faces with fourteen equivalent URb4U8 cuboctahedra. All U–U bond lengths are 3.23 Å.
