Materials Data on Ho2CoGe2 by Materials Project

Abstract

Ho2CoGe2 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 6-coordinate geometry to two equivalent Co and six Ge atoms. Both Ho–Co bond lengths are 3.16 Å. There are a spread of Ho–Ge bond distances ranging from 2.90–3.08 Å. In the second Ho site, Ho is bonded in a 2-coordinate geometry to four equivalent Co and seven Ge atoms. There are a spread of Ho–Co bond distances ranging from 3.02–3.08 Å. There are a spread of Ho–Ge bond distances ranging from 2.91–3.22 Å. Co is bonded in a 10-coordinate geometry to six Ho and four Ge atoms. There are a spread of Co–Ge bond distances ranging from 2.39–2.54 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to seven Ho, one Co, and one Ge atom. The Ge–Ge bond length is 2.68 Å. In the second Ge site, Ge is bonded in a 10-coordinate geometry to six Ho, three equivalent Co, and one Ge atom. The Ge–Ge bond length is 2.82 Å.
