The structure described by MgY is beta-derived structured and crystallizes in the trigonal P-3m1 space group. Mg(1) is bonded to nine equivalent Mg(1) and three equivalent Y(1) atoms to form MgY3Mg9 cuboctahedra that share corners with six equivalent Mg(1)Y3Mg9 cuboctahedra, corners with twelve equivalent Y(1)Y9Mg3 cuboctahedra, edges with six equivalent Y(1)Y9Mg3 cuboctahedra, edges with twelve equivalent Mg(1)Y3Mg9 cuboctahedra, faces with eight equivalent Y(1)Y9Mg3 cuboctahedra, and faces with twelve equivalent Mg(1)Y3Mg9 cuboctahedra. Y(1) is bonded to three equivalent Mg(1) and nine equivalent Y(1) atoms to form YY9Mg3 cuboctahedra that share corners with six equivalent Y(1)Y9Mg3 cuboctahedra, corners with twelve equivalent Mg(1)Y3Mg9 cuboctahedra, edges with six equivalent Mg(1)Y3Mg9 cuboctahedra, edges with twelve equivalent Y(1)Y9Mg3 cuboctahedra, faces with eight equivalent Mg(1)Y3Mg9 cuboctahedra, and faces with twelve equivalent Y(1)Y9Mg3 cuboctahedra. is represented by the CIF card [CIF]
