Materials Data on Sc2Ge4Mo3 by Materials Project

Abstract

Sc2Mo3Ge4 is delta Molybdenum Boride-derived structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Sc is bonded in a 7-coordinate geometry to seven Ge atoms. There are a spread of Sc–Ge bond distances ranging from 2.74–2.95 Å. There are two inequivalent Mo sites. In the first Mo site, Mo is bonded in a 6-coordinate geometry to six Ge atoms. There are a spread of Mo–Ge bond distances ranging from 2.61–2.77 Å. In the second Mo site, Mo is bonded in a 6-coordinate geometry to six Ge atoms. There are a spread of Mo–Ge bond distances ranging from 2.55–2.69 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to four equivalent Sc, four Mo, and one Ge atom. The Ge–Ge bond length is 2.72 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to two equivalent Sc, six Mo, and one Ge atom. The Ge–Ge bond length is 2.63 Å. In the third Ge site, Ge is bonded in a 9-coordinate geometry to four equivalent Sc, four Mo, and one Ge atom.
