The crystal structure described by Rb3Yb is beta-derived structured and crystallizes in the hexagonal P6_3/mmc space group. Rb(1) is bonded to eight equivalent Rb(1) and four equivalent Yb(1) atoms to form distorted RbRb8Yb4 cuboctahedra that share corners with four equivalent Yb(1)Rb12 cuboctahedra, corners with fourteen equivalent Rb(1)Rb8Yb4 cuboctahedra, edges with six equivalent Yb(1)Rb12 cuboctahedra, edges with twelve equivalent Rb(1)Rb8Yb4 cuboctahedra, faces with four equivalent Yb(1)Rb12 cuboctahedra, and faces with sixteen equivalent Rb(1)Rb8Yb4 cuboctahedra. Yb(1) is bonded to twelve equivalent Rb(1) atoms to form YbRb12 cuboctahedra that share corners with six equivalent Yb(1)Rb12 cuboctahedra, corners with twelve equivalent Rb(1)Rb8Yb4 cuboctahedra, edges with eighteen equivalent Rb(1)Rb8Yb4 cuboctahedra, faces with eight equivalent Yb(1)Rb12 cuboctahedra, and faces with twelve equivalent Rb(1)Rb8Yb4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
