Ho Fe Fe Ag
HoFe2Ag crystallizes in the trigonal R3m space group. Ho(1) is bonded in a distorted single-bond geometry to three equivalent Fe(1), three equivalent Fe(2), and one Ag(1) atom. All Ho(1)-Fe(1) bond lengths are 2.72 Å. All Ho(1)-Fe(2) bond lengths are 2.72 Å. The Ho(1)-Ag(1) bond length is 2.08 Å. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 5-coordinate geometry to three equivalent Ho(1), one Fe(2), and one Ag(1) atom. The Fe(1)-Fe(2) bond length is 2.08 Å. The Fe(1)-Ag(1) bond length is 2.40 Å. In the second Fe site, Fe(2) is bonded in a 7-coordinate geometry to three equivalent Ho(1), one Fe(1), and three equivalent Ag(1) atoms. All Fe(2)-Ag(1) bond lengths are 2.72 Å. Ag(1) is bonded in a distorted single-bond geometry to one Ho(1), one Fe(1), and three equivalent Fe(2) atoms.
