Materials Data on Ho3Ge4 by Materials Project
Ho3Ge4 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Ho sites. In the first Ho site, Ho is bonded in a 5-coordinate geometry to seven Ge atoms. There are a spread of Ho–Ge bond distances ranging from 2.89–3.17 Å. In the second Ho site, Ho is bonded in a 8-coordinate geometry to eight Ge atoms. There are a spread of Ho–Ge bond distances ranging from 2.98–3.09 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 4-coordinate geometry to four equivalent Ho and four equivalent Ge atoms. All Ge–Ge bond lengths are 2.85 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to seven Ho and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.61 Å. In the third Ge site, Ge is bonded in a 9-coordinate geometry to six Ho and three Ge atoms.
