Materials Data on Ho3Rh2 by Materials Project

Ho3Rh2 crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. there are five inequivalent Ho sites. In the first Ho site, Ho is bonded in a 6-coordinate geometry to six Rh atoms. There are a spread of Ho–Rh bond distances ranging from 2.88–3.46 Å. In the second Ho site, Ho is bonded in a 4-coordinate geometry to four Rh atoms. There are two shorter (2.71 Å) and two longer (2.83 Å) Ho–Rh bond lengths. In the third Ho site, Ho is bonded to six Rh atoms to form distorted HoRh6 octahedra that share an edgeedge with one HoRh6 octahedra and an edgeedge with one HoRh4 tetrahedra. There are a spread of Ho–Rh bond distances ranging from 2.83–3.21 Å. In the fourth Ho site, Ho is bonded to four equivalent Rh atoms to form edge-sharing HoRh4 tetrahedra. All Ho–Rh bond lengths are 2.89 Å. In the fifth Ho site, Ho is bonded in a 5-coordinate geometry to six Rh atoms. There are a spread of Ho–Rh bond distances ranging from 2.75–3.44 Å. There are six inequivalent Rh sites. In the first Rh site, Rh is bonded in a 8-coordinate geometry to eight Ho atoms. In the second Rh site, Rh is bonded in a 8-coordinate geometry to eight Ho atoms. In the third Rh site, Rh is bonded in a body-centered cubic geometry to eight equivalent Ho atoms. In the fourth Rh site, Rh is bonded in a 10-coordinate geometry to eight equivalent Ho atoms. In the fifth Rh site, Rh is bonded in a 6-coordinate geometry to eight Ho atoms. In the sixth Rh site, Rh is bonded in a 10-coordinate geometry to ten Ho atoms.
