Materials Data on Hf5Sc5Si6 by Materials Project

Abstract

Sc5Hf5Si6 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are three inequivalent Sc sites. In the first Sc site, Sc is bonded in a 5-coordinate geometry to five Si atoms. There are a spread of Sc–Si bond distances ranging from 2.72–3.09 Å. In the second Sc site, Sc is bonded in a 5-coordinate geometry to five Si atoms. There are a spread of Sc–Si bond distances ranging from 2.74–3.09 Å. In the third Sc site, Sc is bonded in a 5-coordinate geometry to five Si atoms. There are a spread of Sc–Si bond distances ranging from 2.72–3.08 Å. There are two inequivalent Hf sites. In the first Hf site, Hf is bonded in a 6-coordinate geometry to six Si atoms. There are a spread of Hf–Si bond distances ranging from 2.80–2.82 Å. In the second Hf site, Hf is bonded in a 5-coordinate geometry to five Si atoms. There are a spread of Hf–Si bond distances ranging from 2.73–3.07 Å. There are four inequivalent Si sites. In the first Si site, Si is bonded in a 9-coordinate geometry to four Sc and five Hf atoms. In the second Si site, Si is bonded in a 9-coordinate geometry to four Sc and five Hf atoms. In the third Si site, Si is bonded in a 9-coordinate geometry to three Sc and six Hf atoms. In the fourth Si site, Si is bonded in a 9-coordinate geometry to five Sc and four equivalent Hf atoms.
