Materials Data on Ho3(GeRh)2 by Materials Project

Abstract

Ho3(RhGe)2 crystallizes in the orthorhombic Pbcm space group. The structure is three-dimensional. there are two inequivalent Ho sites. In the first Ho site, Ho is bonded in a 9-coordinate geometry to four equivalent Rh and five Ge atoms. There are two shorter (3.02 Å) and two longer (3.05 Å) Ho–Rh bond lengths. There are a spread of Ho–Ge bond distances ranging from 2.99–3.30 Å. In the second Ho site, Ho is bonded in a 7-coordinate geometry to four equivalent Rh and five Ge atoms. There are a spread of Ho–Rh bond distances ranging from 2.90–3.13 Å. There are a spread of Ho–Ge bond distances ranging from 2.98–3.34 Å. Rh is bonded in a 9-coordinate geometry to six Ho and three Ge atoms. There are a spread of Rh–Ge bond distances ranging from 2.54–2.60 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to seven Ho and two equivalent Rh atoms. In the second Ge site, Ge is bonded in a 12-coordinate geometry to eight Ho and four equivalent Rh atoms.
