The structure described by ThY is Magnesium-derived structured and crystallizes in the hexagonal P-6m2 space group. Th(1) is bonded to six equivalent Th(1) and six equivalent Y(1) atoms to form ThY6Th6 cuboctahedra that share corners with eighteen equivalent Th(1)Y6Th6 cuboctahedra, edges with six equivalent Th(1)Y6Th6 cuboctahedra, edges with twelve equivalent Y(1)Y6Th6 cuboctahedra, faces with eight equivalent Th(1)Y6Th6 cuboctahedra, and faces with twelve equivalent Y(1)Y6Th6 cuboctahedra. Y(1) is bonded to six equivalent Th(1) and six equivalent Y(1) atoms to form YY6Th6 cuboctahedra that share corners with eighteen equivalent Y(1)Y6Th6 cuboctahedra, edges with six equivalent Y(1)Y6Th6 cuboctahedra, edges with twelve equivalent Th(1)Y6Th6 cuboctahedra, faces with eight equivalent Y(1)Y6Th6 cuboctahedra, and faces with twelve equivalent Th(1)Y6Th6 cuboctahedra. is represented by the CIF card [CIF]
