Materials Data on Tb2Ge2Ru by Materials Project
Tb2RuGe2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Tb sites. In the first Tb site, Tb is bonded in a 6-coordinate geometry to two equivalent Ru and six Ge atoms. Both Tb–Ru bond lengths are 3.28 Å. There are a spread of Tb–Ge bond distances ranging from 2.93–3.25 Å. In the second Tb site, Tb is bonded in a 2-coordinate geometry to four equivalent Ru and seven Ge atoms. There are a spread of Tb–Ru bond distances ranging from 3.10–3.18 Å. There are a spread of Tb–Ge bond distances ranging from 2.95–3.48 Å. Ru is bonded in a 10-coordinate geometry to six Tb 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 Tb, three equivalent Ru, and one Ge atom. The Ge–Ge bond length is 2.79 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to seven Tb, one Ru, and one Ge atom. The Ge–Ge bond length is 2.68 Å.
