The structure described by Th2Dy is alpha La-derived structured and crystallizes in the trigonal P-3m1 space group. Th(1) is bonded to nine equivalent Th(1) and three equivalent Dy(1) atoms to form ThDy3Th9 cuboctahedra that share corners with three equivalent Dy(1)Dy6Th6 cuboctahedra, corners with nine equivalent Th(1)Dy3Th9 cuboctahedra, edges with nine equivalent Dy(1)Dy6Th6 cuboctahedra, edges with fifteen equivalent Th(1)Dy3Th9 cuboctahedra, faces with six equivalent Dy(1)Dy6Th6 cuboctahedra, and faces with twelve equivalent Th(1)Dy3Th9 cuboctahedra. Dy(1) is bonded to six equivalent Th(1) and six equivalent Dy(1) atoms to form DyDy6Th6 cuboctahedra that share corners with six equivalent Th(1)Dy3Th9 cuboctahedra, corners with six equivalent Dy(1)Dy6Th6 cuboctahedra, edges with six equivalent Dy(1)Dy6Th6 cuboctahedra, edges with eighteen equivalent Th(1)Dy3Th9 cuboctahedra, faces with six equivalent Dy(1)Dy6Th6 cuboctahedra, and faces with twelve equivalent Th(1)Dy3Th9 cuboctahedra. is represented by the CIF file [CIF]
