TbFe2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. Tb(1) is bonded in a 12-coordinate geometry to three equivalent Fe(1) and nine equivalent Fe(2) atoms. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to six equivalent Tb(1) and six equivalent Fe(2) atoms to form a mixture of face, corner, and edge-sharing FeTb6Fe6 cuboctahedra. In the second Fe site, Fe(2) is bonded to six equivalent Tb(1), two equivalent Fe(1), and four equivalent Fe(2) atoms to form a mixture of face, corner, and edge-sharing FeTb6Fe6 cuboctahedra.
TbFe2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. Tb(1) is bonded in a 12-coordinate geometry to three equivalent Fe(1) and nine equivalent Fe(2) atoms. All Tb(1)-Fe(1) bond lengths are 3.05 Å. All Tb(1)-Fe(2) bond lengths are 3.04 Å. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to six equivalent Tb(1) and six equivalent Fe(2) atoms to form a mixture of face, corner, and edge-sharing FeTb6Fe6 cuboctahedra. All Fe(1)-Fe(2) bond lengths are 2.57 Å. In the second Fe site, Fe(2) is bonded to six equivalent Tb(1), two equivalent Fe(1), and four equivalent Fe(2) atoms to form a mixture of face, corner, and edge-sharing FeTb6Fe6 cuboctahedra. There are two shorter (2.57 Å) and two longer (2.63 Å) Fe(2)-Fe(2) bond lengths.
