The material structure described by TmNd2 is beta-derived structured and crystallizes in the trigonal R-3m space group. Tm(1) is bonded to six equivalent Tm(1) and six equivalent Nd(1) atoms to form TmNd6Tm6 cuboctahedra that share corners with six equivalent Tm(1)Nd6Tm6 cuboctahedra, corners with twelve equivalent Nd(1)Nd9Tm3 cuboctahedra, edges with six equivalent Tm(1)Nd6Tm6 cuboctahedra, edges with twelve equivalent Nd(1)Nd9Tm3 cuboctahedra, faces with six equivalent Tm(1)Nd6Tm6 cuboctahedra, and faces with fourteen equivalent Nd(1)Nd9Tm3 cuboctahedra. Nd(1) is bonded to three equivalent Tm(1) and nine equivalent Nd(1) atoms to form NdNd9Tm3 cuboctahedra that share corners with six equivalent Tm(1)Nd6Tm6 cuboctahedra, corners with nine equivalent Nd(1)Nd9Tm3 cuboctahedra, edges with six equivalent Tm(1)Nd6Tm6 cuboctahedra, edges with fifteen equivalent Nd(1)Nd9Tm3 cuboctahedra, faces with seven equivalent Tm(1)Nd6Tm6 cuboctahedra, and faces with twelve equivalent Nd(1)Nd9Tm3 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
