Materials Data on HoGe3 by Materials Project
HoGe3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Ho is bonded in a 10-coordinate geometry to ten Ge atoms. There are a spread of Ho–Ge bond distances ranging from 2.96–3.26 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 8-coordinate geometry to six equivalent Ho and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.58 Å. In the second Ge site, Ge is bonded in a 7-coordinate geometry to two equivalent Ho and five equivalent Ge atoms. There are one shorter (2.50 Å) and four longer (2.82 Å) Ge–Ge bond lengths. In the third Ge site, Ge is bonded in a 7-coordinate geometry to two equivalent Ho and five equivalent Ge atoms.
