Materials Data on Er3Ge3Ru2 by Materials Project

Abstract

Er3Ru2Ge3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Er sites. In the first Er site, Er is bonded in a 10-coordinate geometry to four equivalent Ru and six Ge atoms. There are a spread of Er–Ru bond distances ranging from 3.09–3.15 Å. There are a spread of Er–Ge bond distances ranging from 2.98–3.13 Å. In the second Er site, Er is bonded in a 9-coordinate geometry to four equivalent Ru and five Ge atoms. All Er–Ru bond lengths are 3.22 Å. There are a spread of Er–Ge bond distances ranging from 2.92–3.31 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 2.45–2.67 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to five Er, three equivalent Ru, and one Ge atom. The Ge–Ge bond length is 2.71 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to seven Er and two equivalent Ru atoms.
