The structure described by Pu3Y is Magnesium-derived structured and crystallizes in the hexagonal P6_3/mmc space group. There are three inequivalent Pu sites. In the first Pu site, Pu(1) is bonded to eight Pu(1,1) and four equivalent Y(1) atoms to form PuY4Pu8 cuboctahedra that share corners with four equivalent Y(1)Pu12 cuboctahedra; corners with fourteen Pu(1,1,1)Y4Pu8 cuboctahedra; edges with six equivalent Y(1)Pu12 cuboctahedra; edges with twelve Pu(1,1)Y4Pu8 cuboctahedra; faces with four equivalent Y(1)Pu12 cuboctahedra; and faces with sixteen Pu(1,1,1)Y4Pu8 cuboctahedra. In the second Pu site, Pu(1) is bonded to eight Pu(1,1) and four equivalent Y(1) atoms to form PuY4Pu8 cuboctahedra that share corners with four equivalent Y(1)Pu12 cuboctahedra; corners with fourteen Pu(1,1,1)Y4Pu8 cuboctahedra; edges with six equivalent Y(1)Pu12 cuboctahedra; edges with twelve Pu(1,1)Y4Pu8 cuboctahedra; faces with four equivalent Y(1)Pu12 cuboctahedra; and faces with sixteen Pu(1,1,1)Y4Pu8 cuboctahedra.
