The crystal structure described by Tb2FeCo3 is Hexagonal Laves-derived structured and crystallizes in the trigonal R-3m space group. Tb(1) is bonded in a 12-coordinate geometry to three equivalent Fe(1) and nine equivalent Co(1) atoms. Fe(1) is bonded to six equivalent Tb(1) and six equivalent Co(1) atoms to form FeTb6Co6 cuboctahedra that share corners with six equivalent Fe(1)Tb6Co6 cuboctahedra, corners with twelve equivalent Co(1)Tb6Fe2Co4 cuboctahedra, edges with six equivalent Fe(1)Tb6Co6 cuboctahedra, and faces with eighteen equivalent Co(1)Tb6Fe2Co4 cuboctahedra. Co(1) is bonded to six equivalent Tb(1), two equivalent Fe(1), and four equivalent Co(1) atoms to form CoTb6Fe2Co4 cuboctahedra that share corners with four equivalent Fe(1)Tb6Co6 cuboctahedra, corners with fourteen equivalent Co(1)Tb6Fe2Co4 cuboctahedra, edges with six equivalent Co(1)Tb6Fe2Co4 cuboctahedra, faces with six equivalent Fe(1)Tb6Co6 cuboctahedra, and faces with twelve equivalent Co(1)Tb6Fe2Co4 cuboctahedra. is represented by the CIF file [CIF]
