Materials Data on HoInRh by Materials Project

HoRhIn crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Ho is bonded in a 11-coordinate geometry to five Rh and six equivalent In atoms. There are four shorter (3.01 Å) and one longer (3.05 Å) Ho–Rh bond lengths. There are two shorter (3.20 Å) and four longer (3.32 Å) Ho–In bond lengths. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 9-coordinate geometry to six equivalent Ho and three equivalent In atoms. All Rh–In bond lengths are 2.83 Å. In the second Rh site, Rh is bonded in a 9-coordinate geometry to three equivalent Ho and six equivalent In atoms. All Rh–In bond lengths are 2.76 Å. In is bonded in a 4-coordinate geometry to six equivalent Ho and four Rh atoms.

Materials Data on HoIn5Rh by Materials Project

HoRhIn5 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Ho is bonded to twelve In atoms to form HoIn12 cuboctahedra that share corners with four equivalent HoIn12 cuboctahedra, faces with four equivalent HoIn12 cuboctahedra, and faces with four equivalent InHo4In8 cuboctahedra. There are eight shorter (3.25 Å) and four longer (3.29 Å) Ho–In bond lengths. Rh is bonded in a body-centered cubic geometry to eight equivalent In atoms. All Rh–In bond lengths are 2.77 Å. There are two inequivalent In sites. In the first In site, In is bonded to four equivalent Ho and eight equivalent In atoms to form distorted InHo4In8 cuboctahedra that share corners with four equivalent InHo4In8 cuboctahedra, faces with four equivalent HoIn12 cuboctahedra, and faces with four equivalent InHo4In8 cuboctahedra. All In–In bond lengths are 3.25 Å. In the second In site, In is bonded in a 4-coordinate geometry to two equivalent Ho, two equivalent Rh, and two equivalent In atoms.
