Materials Data on Tb3(GeRh)2 by Materials Project

Abstract

Tb3(RhGe)2 crystallizes in the orthorhombic Pbcm space group. The structure is three-dimensional. there are two inequivalent Tb sites. In the first Tb site, Tb is bonded in a 9-coordinate geometry to four equivalent Rh and five Ge atoms. There are two shorter (3.04 Å) and two longer (3.08 Å) Tb–Rh bond lengths. There are a spread of Tb–Ge bond distances ranging from 3.03–3.32 Å. In the second Tb site, Tb is bonded in a 7-coordinate geometry to four equivalent Rh and five Ge atoms. There are a spread of Tb–Rh bond distances ranging from 2.92–3.15 Å. There are a spread of Tb–Ge bond distances ranging from 3.01–3.37 Å. Rh is bonded in a 9-coordinate geometry to six Tb and three Ge atoms. There are a spread of Rh–Ge bond distances ranging from 2.55–2.62 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to seven Tb and two equivalent Rh atoms. In the second Ge site, Ge is bonded in a 12-coordinate geometry to eight Tb and four equivalent Rh atoms.
