Materials Data on Ho2Ge2Rh by Materials Project

Abstract

Ho2RhGe2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Ho sites. In the first Ho site, Ho is bonded in a 8-coordinate geometry to two equivalent Rh and six Ge atoms. Both Ho–Rh bond lengths are 3.05 Å. There are a spread of Ho–Ge bond distances ranging from 2.99–3.09 Å. In the second Ho site, Ho is bonded in a 11-coordinate geometry to four equivalent Rh and seven Ge atoms. There are a spread of Ho–Rh bond distances ranging from 3.01–3.25 Å. There are a spread of Ho–Ge bond distances ranging from 2.98–3.30 Å. Rh is bonded in a 10-coordinate geometry to six Ho and four Ge atoms. There are a spread of Rh–Ge bond distances ranging from 2.50–2.72 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to seven Ho, one Rh, and one Ge atom. The Ge–Ge bond length is 2.63 Å. In the second Ge site, Ge is bonded in a 10-coordinate geometry to six Ho, three equivalent Rh, and one Ge atom. The Ge–Ge bond length is 2.69 Å.
