Materials Data on Tm3(GeRh)2 by Materials Project
Tm3(RhGe)2 crystallizes in the orthorhombic Pbcm space group. The structure is three-dimensional. there are two inequivalent Tm sites. In the first Tm site, Tm is bonded in a 9-coordinate geometry to four equivalent Rh and five Ge atoms. There are two shorter (2.99 Å) and two longer (3.02 Å) Tm–Rh bond lengths. There are a spread of Tm–Ge bond distances ranging from 2.96–3.28 Å. In the second Tm site, Tm is bonded in a 7-coordinate geometry to four equivalent Rh and five Ge atoms. There are a spread of Tm–Rh bond distances ranging from 2.87–3.10 Å. There are a spread of Tm–Ge bond distances ranging from 2.96–3.33 Å. Rh is bonded in a 9-coordinate geometry to six Tm and three Ge atoms. There are a spread of Rh–Ge bond distances ranging from 2.53–2.59 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to seven Tm and two equivalent Rh atoms. In the second Ge site, Ge is bonded in a 12-coordinate geometry to eight Tm and four equivalent Rh atoms.
