Materials Data on Tb3Ge3Ru2 by Materials Project

Abstract

Tb3Ru2Ge3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Tb sites. In the first 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 3.10–3.23 Å. There are a spread of Tb–Ge bond distances ranging from 3.04–3.46 Å. In the second Tb site, Tb is bonded in a 4-coordinate geometry to four equivalent Ru and five Ge atoms. All Tb–Ru bond lengths are 3.29 Å. There are a spread of Tb–Ge bond distances ranging from 2.95–3.42 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 2.46–2.71 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 2.83 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to seven Tb and two equivalent Ru atoms.
