Materials Data on Ho2Ge2Ru by Materials Project
Ho2RuGe2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Ho sites. In the first Ho site, Ho is bonded in a 2-coordinate geometry to four equivalent Ru and seven Ge atoms. There are a spread of Ho–Ru bond distances ranging from 3.06–3.17 Å. There are a spread of Ho–Ge bond distances ranging from 2.94–3.43 Å. In the second Ho site, Ho is bonded in a 6-coordinate geometry to two equivalent Ru and six Ge atoms. Both Ho–Ru bond lengths are 3.28 Å. There are a spread of Ho–Ge bond distances ranging from 2.90–3.20 Å. Ru is bonded in a 10-coordinate geometry to six Ho and four Ge atoms. There are a spread of Ru–Ge bond distances ranging from 2.46–2.62 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 10-coordinate geometry to six Ho, three equivalent Ru, and one Ge atom. The Ge–Ge bond length is 2.75 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to seven Ho, one Ru, and one Ge atom. The Ge–Ge bond length is 2.66 Å.
