The structure described by Yb3Tb is Magnesium-derived structured and crystallizes in the hexagonal P6_3/mmc space group. Yb(1) is bonded to eight equivalent Yb(1) and four equivalent Tb(1) atoms to form YbTb4Yb8 cuboctahedra that share corners with four equivalent Tb(1)Yb12 cuboctahedra, corners with fourteen equivalent Yb(1)Tb4Yb8 cuboctahedra, edges with six equivalent Tb(1)Yb12 cuboctahedra, edges with twelve equivalent Yb(1)Tb4Yb8 cuboctahedra, faces with four equivalent Tb(1)Yb12 cuboctahedra, and faces with sixteen equivalent Yb(1)Tb4Yb8 cuboctahedra. Tb(1) is bonded to twelve equivalent Yb(1) atoms to form TbYb12 cuboctahedra that share corners with six equivalent Tb(1)Yb12 cuboctahedra, corners with twelve equivalent Yb(1)Tb4Yb8 cuboctahedra, edges with eighteen equivalent Yb(1)Tb4Yb8 cuboctahedra, faces with eight equivalent Tb(1)Yb12 cuboctahedra, and faces with twelve equivalent Yb(1)Tb4Yb8 cuboctahedra. is represented by the CIF card [CIF]
