Materials Data on Er2Ge2Ru by Materials Project

Abstract

Er2RuGe2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Er sites. In the first Er site, Er is bonded in a 2-coordinate geometry to four equivalent Ru and seven Ge atoms. There are a spread of Er–Ru bond distances ranging from 3.05–3.15 Å. There are a spread of Er–Ge bond distances ranging from 2.93–3.41 Å. In the second Er site, Er is bonded in a 6-coordinate geometry to two equivalent Ru and six Ge atoms. Both Er–Ru bond lengths are 3.27 Å. There are a spread of Er–Ge bond distances ranging from 2.90–3.17 Å. Ru is bonded in a 10-coordinate geometry to six Er and four Ge atoms. There are a spread of Ru–Ge bond distances ranging from 2.45–2.61 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 10-coordinate geometry to six Er, three equivalent Ru, and one Ge atom. The Ge–Ge bond length is 2.72 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to seven Er, one Ru, and one Ge atom. The Ge–Ge bond length is 2.65 Å.
