Materials Data on EuSi6 by Materials Project

Abstract

EuSi6 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Eu is bonded in a 8-coordinate geometry to eighteen Si atoms. There are a spread of Eu–Si bond distances ranging from 3.12–3.51 Å. There are three inequivalent Si sites. In the first Si site, Si is bonded in a 7-coordinate geometry to three equivalent Eu and four Si atoms. There are a spread of Si–Si bond distances ranging from 2.37–2.44 Å. In the second Si site, Si is bonded in a 7-coordinate geometry to three equivalent Eu and four Si atoms. All Si–Si bond lengths are 2.41 Å. In the third Si site, Si is bonded in a 4-coordinate geometry to three equivalent Eu and four Si atoms. The Si–Si bond length is 2.41 Å.
