Materials Data on Sc3(FeSi3)2 by Materials Project
Abstract
Sc3(FeSi3)2 crystallizes in the orthorhombic Cmce space group. The structure is three-dimensional. there are three inequivalent Sc sites. In the first Sc site, Sc is bonded in a 6-coordinate geometry to eight Si atoms. There are a spread of Sc–Si bond distances ranging from 2.71–2.92 Å. In the second Sc site, Sc is bonded in a 7-coordinate geometry to two equivalent Fe and seven Si atoms. Both Sc–Fe bond lengths are 2.99 Å. There are a spread of Sc–Si bond distances ranging from 2.69–2.89 Å. In the third Sc site, Sc is bonded in a 12-coordinate geometry to four Fe and eight Si atoms. There are two shorter (2.94 Å) and two longer (2.97 Å) Sc–Fe bond lengths. There are a spread of Sc–Si bond distances ranging from 2.65–2.93 Å. There are two inequivalent Fe sites. In the first Fe site, Fe is bonded in a 12-coordinate geometry to two equivalent Sc and six Si atoms. There are a spread of Fe–Si bond distances ranging from 2.32–2.45 Å. In the second Fe site, Fe is bonded to four Sc, two equivalent Fe, and six Si atoms to form a mixture of distorted corner and face-sharing FeSc4Fe2Si6 cuboctahedra. Both Fe–Fe bondmore »
