Materials Data on Rb3Sm by Materials Project

Abstract

Rb3Sm 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 Sm atoms to form RbRb8Sm4 cuboctahedra that share corners with twelve equivalent RbRb8Sm4 cuboctahedra, edges with eight equivalent SmRb12 cuboctahedra, edges with sixteen equivalent RbRb8Sm4 cuboctahedra, faces with four equivalent SmRb12 cuboctahedra, and faces with fourteen equivalent RbRb8Sm4 cuboctahedra. All Rb–Rb bond lengths are 4.55 Å. All Rb–Sm bond lengths are 4.55 Å. Sm is bonded to twelve equivalent Rb atoms to form SmRb12 cuboctahedra that share corners with twelve equivalent SmRb12 cuboctahedra, edges with twenty-four equivalent RbRb8Sm4 cuboctahedra, faces with six equivalent SmRb12 cuboctahedra, and faces with twelve equivalent RbRb8Sm4 cuboctahedra.
