Materials Data on Ho2Ge5Rh3 by Materials Project
Ho2Rh3Ge5 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Ho is bonded in a 8-coordinate geometry to six Rh and ten Ge atoms. There are a spread of Ho–Rh bond distances ranging from 3.17–3.58 Å. There are a spread of Ho–Ge bond distances ranging from 3.04–3.40 Å. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 9-coordinate geometry to four equivalent Ho and five Ge atoms. There are a spread of Rh–Ge bond distances ranging from 2.41–2.57 Å. In the second Rh site, Rh is bonded in a 6-coordinate geometry to four equivalent Ho and six Ge atoms. There are a spread of Rh–Ge bond distances ranging from 2.50–2.75 Å. There are four inequivalent Ge sites. In the first Ge site, Ge is bonded in a 4-coordinate geometry to four equivalent Ho and four equivalent Rh atoms. In the second Ge site, Ge is bonded in a 5-coordinate geometry to four equivalent Ho, three Rh, and four Ge atoms. There are two shorter (2.69 Å) and two longer (2.95 Å) Ge–Ge bond lengths. In the third Ge site, Ge is bonded in a 2-coordinate geometry to four equivalent Ho, three Rh, and four Ge atoms. Both Ge–Ge bond lengths are 2.69 Å. In the fourth Ge site, Ge is bonded in a 9-coordinate geometry to four equivalent Ho, three Rh, and two Ge atoms.
