Materials Data on Sc2CoGe2 by Materials Project

Abstract

Sc2CoGe2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Sc sites. In the first Sc site, Sc is bonded in a 2-coordinate geometry to four equivalent Co and seven Ge atoms. There are a spread of Sc–Co bond distances ranging from 2.87–3.01 Å. There are a spread of Sc–Ge bond distances ranging from 2.75–3.17 Å. In the second Sc site, Sc is bonded in a 6-coordinate geometry to two equivalent Co and six Ge atoms. Both Sc–Co bond lengths are 3.12 Å. There are a spread of Sc–Ge bond distances ranging from 2.73–2.93 Å. Co is bonded in a 4-coordinate geometry to six Sc and four Ge atoms. There are a spread of Co–Ge bond distances ranging from 2.32–2.45 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 10-coordinate geometry to six Sc, three equivalent Co, and one Ge atom. The Ge–Ge bond length is 2.61 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to seven Sc, one Co, and one Ge atom. The Ge–Ge bond length is 2.62 Å.
