SrLu crystallizes in the hexagonal P-6m2 space group. Sr(1) is bonded to six equivalent Sr(1) and six equivalent Lu(1) atoms to form SrSr6Lu6 cuboctahedra that share corners with eighteen equivalent Sr(1)Sr6Lu6 cuboctahedra, edges with six equivalent Sr(1)Sr6Lu6 cuboctahedra, edges with twelve equivalent Lu(1)Sr6Lu6 cuboctahedra, faces with eight equivalent Sr(1)Sr6Lu6 cuboctahedra, and faces with twelve equivalent Lu(1)Sr6Lu6 cuboctahedra. Lu(1) is bonded to six equivalent Sr(1) and six equivalent Lu(1) atoms to form LuSr6Lu6 cuboctahedra that share corners with eighteen equivalent Lu(1)Sr6Lu6 cuboctahedra, edges with six equivalent Lu(1)Sr6Lu6 cuboctahedra, edges with twelve equivalent Sr(1)Sr6Lu6 cuboctahedra, faces with eight equivalent Lu(1)Sr6Lu6 cuboctahedra, and faces with twelve equivalent Sr(1)Sr6Lu6 cuboctahedra.
