Rh3Sb is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Rh(1) is bonded to eight equivalent Rh(1) and four equivalent Sb(1) atoms to form RhSb4Rh8 cuboctahedra that share corners with twelve equivalent Rh(1)Sb4Rh8 cuboctahedra, edges with eight equivalent Sb(1)Rh12 cuboctahedra, edges with sixteen equivalent Rh(1)Sb4Rh8 cuboctahedra, faces with four equivalent Sb(1)Rh12 cuboctahedra, and faces with fourteen equivalent Rh(1)Sb4Rh8 cuboctahedra. Sb(1) is bonded to twelve equivalent Rh(1) atoms to form SbRh12 cuboctahedra that share corners with twelve equivalent Sb(1)Rh12 cuboctahedra, edges with twenty-four equivalent Rh(1)Sb4Rh8 cuboctahedra, faces with six equivalent Sb(1)Rh12 cuboctahedra, and faces with twelve equivalent Rh(1)Sb4Rh8 cuboctahedra.
