Materials Data on ScCrGe2 by Materials Project

Abstract

ScCrGe2 crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. there are two inequivalent Sc sites. In the first Sc site, Sc is bonded in a 8-coordinate geometry to eight Ge atoms. There are a spread of Sc–Ge bond distances ranging from 2.78–2.99 Å. In the second Sc site, Sc is bonded in a 7-coordinate geometry to seven Ge atoms. There are a spread of Sc–Ge bond distances ranging from 2.78–2.93 Å. There are two inequivalent Cr sites. In the first Cr site, Cr is bonded in a 12-coordinate geometry to six Ge atoms. There are a spread of Cr–Ge bond distances ranging from 2.48–2.60 Å. In the second Cr site, Cr is bonded in a 12-coordinate geometry to six Ge atoms. There are a spread of Cr–Ge bond distances ranging from 2.56–2.58 Å. There are five inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to six Sc, two equivalent Cr, and one Ge atom. The Ge–Ge bond length is 2.56 Å. In the second Ge site, Ge is bonded in a 2-coordinate geometry to four equivalent Sc, two equivalent Cr, and one Ge atom. The Ge–Ge bond length is 2.61 Å. In the third Ge site, Ge is bonded in a 9-coordinate geometry to five Sc and four Cr atoms. In the fourth Ge site, Ge is bonded in a 6-coordinate geometry to two equivalent Sc and four Cr atoms. In the fifth Ge site, Ge is bonded in a 7-coordinate geometry to three Sc, three Cr, and one Ge atom. The Ge–Ge bond length is 2.61 Å.
