Materials Data on Rb3Er by Materials Project

Abstract

Rb3Er 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 Er atoms to form distorted RbRb8Er4 cuboctahedra that share corners with twelve equivalent RbRb8Er4 cuboctahedra, edges with eight equivalent ErRb12 cuboctahedra, edges with sixteen equivalent RbRb8Er4 cuboctahedra, faces with four equivalent ErRb12 cuboctahedra, and faces with fourteen equivalent RbRb8Er4 cuboctahedra. All Rb–Rb bond lengths are 4.55 Å. All Rb–Er bond lengths are 4.55 Å. Er is bonded to twelve equivalent Rb atoms to form ErRb12 cuboctahedra that share corners with twelve equivalent ErRb12 cuboctahedra, edges with twenty-four equivalent RbRb8Er4 cuboctahedra, faces with six equivalent ErRb12 cuboctahedra, and faces with twelve equivalent RbRb8Er4 cuboctahedra.
