Materials Data on Dy3Fe2Si3 by Materials Project

Abstract

Dy3Fe2Si3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Dy sites. In the first Dy site, Dy is bonded in a 10-coordinate geometry to four equivalent Fe and seven Si atoms. There are a spread of Dy–Fe bond distances ranging from 2.98–3.15 Å. There are a spread of Dy–Si bond distances ranging from 2.94–3.25 Å. In the second Dy site, Dy is bonded in a 4-coordinate geometry to four equivalent Fe and five Si atoms. All Dy–Fe bond lengths are 3.19 Å. There are a spread of Dy–Si bond distances ranging from 2.85–3.29 Å. Fe is bonded in a 10-coordinate geometry to six Dy and four Si atoms. There are a spread of Fe–Si bond distances ranging from 2.31–2.57 Å. There are two inequivalent Si sites. In the first Si site, Si is bonded in a 10-coordinate geometry to six Dy, three equivalent Fe, and one Si atom. The Si–Si bond length is 2.87 Å. In the second Si site, Si is bonded in a 9-coordinate geometry to seven Dy and two equivalent Fe atoms.
