The compound described by Lu3Y is Magnesium-derived structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded to eight Lu(1,1) and four equivalent Y(1) atoms to form LuY4Lu8 cuboctahedra that share corners with four equivalent Y(1)Lu12 cuboctahedra; corners with fourteen Lu(1,1)Y4Lu8 cuboctahedra; edges with six equivalent Y(1)Lu12 cuboctahedra; edges with twelve Lu(1,1)Y4Lu8 cuboctahedra; faces with four equivalent Y(1)Lu12 cuboctahedra; and faces with sixteen Lu(1,1)Y4Lu8 cuboctahedra. In the second Lu site, Lu(1) is bonded to eight Lu(1,1) and four equivalent Y(1) atoms to form LuY4Lu8 cuboctahedra that share corners with four equivalent Y(1)Lu12 cuboctahedra; corners with fourteen Lu(1,1)Y4Lu8 cuboctahedra; edges with six equivalent Y(1)Lu12 cuboctahedra; edges with twelve Lu(1,1)Y4Lu8 cuboctahedra; faces with four equivalent Y(1)Lu12 cuboctahedra; and faces with sixteen Lu(1,1)Y4Lu8 cuboctahedra.
