The material described by SrYb crystallizes in the hexagonal P-6m2 space group. Sr(1) is bonded to six equivalent Sr(1) and six equivalent Yb(1) atoms to form SrSr6Yb6 cuboctahedra that share corners with eighteen equivalent Sr(1)Sr6Yb6 cuboctahedra, edges with six equivalent Sr(1)Sr6Yb6 cuboctahedra, edges with twelve equivalent Yb(1)Sr6Yb6 cuboctahedra, faces with eight equivalent Sr(1)Sr6Yb6 cuboctahedra, and faces with twelve equivalent Yb(1)Sr6Yb6 cuboctahedra. Yb(1) is bonded to six equivalent Sr(1) and six equivalent Yb(1) atoms to form YbSr6Yb6 cuboctahedra that share corners with eighteen equivalent Yb(1)Sr6Yb6 cuboctahedra, edges with six equivalent Yb(1)Sr6Yb6 cuboctahedra, edges with twelve equivalent Sr(1)Sr6Yb6 cuboctahedra, faces with eight equivalent Yb(1)Sr6Yb6 cuboctahedra, and faces with twelve equivalent Sr(1)Sr6Yb6 cuboctahedra. is represented by the CIF file [CIF]
