Ho7FeI12 is trigonal omega-derived structured and crystallizes in the trigonal R-3 space group. The structure is three-dimensional. there are two inequivalent Ho sites. In the first Ho site, Ho is bonded to one Fe and five I atoms to form a mixture of distorted edge and corner-sharing HoFeI5 octahedra. The corner-sharing octahedra tilt angles range from 0–9°. The Ho–Fe bond length is 2.59 Å. There are a spread of Ho–I bond distances ranging from 3.08–3.50 Å. In the second Ho site, Ho is bonded to six equivalent I atoms to form edge-sharing HoI6 octahedra. All Ho–I bond lengths are 3.03 Å. Fe is bonded in an octahedral geometry to six equivalent Ho atoms. There are two inequivalent I sites. In the first I site, I is bonded in a distorted T-shaped geometry to three Ho atoms. In the second I site, I is bonded in a 3-coordinate geometry to three equivalent Ho atoms.

Materials Data on Ho5Co2Bi by Materials Project

Ho5Co2Bi crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. there are two inequivalent Ho sites. In the first Ho site, Ho is bonded to three equivalent Co and two equivalent Bi atoms to form a mixture of distorted edge, face, and corner-sharing HoCo3Bi2 square pyramids. There are one shorter (2.83 Å) and two longer (2.86 Å) Ho–Co bond lengths. Both Ho–Bi bond lengths are 3.32 Å. In the second Ho site, Ho is bonded in a 4-coordinate geometry to four equivalent Co and two equivalent Bi atoms. All Ho–Co bond lengths are 2.93 Å. Both Ho–Bi bond lengths are 3.55 Å. Co is bonded in a 8-coordinate geometry to eight Ho atoms. Bi is bonded in a 10-coordinate geometry to ten Ho atoms.
