The structure described by Pu3Tb is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Pu sites. In the first Pu site, Pu(1) is bonded to eight Pu(1,1) and four equivalent Tb(1) atoms to form PuTb4Pu8 cuboctahedra that share corners with four equivalent Tb(1)Pu12 cuboctahedra; corners with fourteen Pu(1,1)Tb4Pu8 cuboctahedra; edges with six equivalent Tb(1)Pu12 cuboctahedra; edges with twelve Pu(1,1)Tb4Pu8 cuboctahedra; faces with four equivalent Tb(1)Pu12 cuboctahedra; and faces with sixteen Pu(1,1)Tb4Pu8 cuboctahedra. In the second Pu site, Pu(1) is bonded to eight equivalent Pu(1) and four equivalent Tb(1) atoms to form PuTb4Pu8 cuboctahedra that share corners with four equivalent Tb(1)Pu12 cuboctahedra; corners with fourteen Pu(1,1)Tb4Pu8 cuboctahedra; edges with six equivalent Tb(1)Pu12 cuboctahedra; edges with twelve equivalent Pu(1)Tb4Pu8 cuboctahedra; faces with four equivalent Tb(1)Pu12 cuboctahedra; and faces with sixteen Pu(1,1)Tb4Pu8 cuboctahedra. Tb(1) is bonded to twelve Pu(1,1) atoms to form TbPu12 cuboctahedra that share corners with six equivalent Tb(1)Pu12 cuboctahedra; corners with twelve Pu(1,1)Tb4Pu8 cuboctahedra; edges with eighteen Pu(1,1)Tb4Pu8 cuboctahedra; faces with eight equivalent Tb(1)Pu12 cuboctahedra; and faces with twelve Pu(1,1)Tb4Pu8 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
