Tb Ho Fe Fe
HoTbFe2 crystallizes in the trigonal R3m space group. Ho(1) is bonded in a 11-coordinate geometry to three equivalent Tb(1), four equivalent Fe(1), and four equivalent Fe(2) atoms. All Ho(1)-Tb(1) bond lengths are 2.75 Å. There are three shorter (2.74 Å) and one longer (3.74 Å) Ho(1)-Fe(1) bond length. There are three shorter (2.74 Å) and one longer (3.74 Å) Ho(1)-Fe(2) bond length. Tb(1) is bonded in a single-bond geometry to three equivalent Ho(1), one Fe(2), and four equivalent Fe(1) atoms. The Tb(1)-Fe(2) bond length is 0.41 Å. There are three shorter (2.74 Å) and one longer (3.74 Å) Tb(1)-Fe(1) bond length. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 8-coordinate geometry to four equivalent Ho(1) and four equivalent Tb(1) atoms. In the second Fe site, Fe(2) is bonded in a single-bond geometry to four equivalent Ho(1) and one Tb(1) atom.
