Materials Data on EuIn4Au by Materials Project

Abstract

EuAuIn4 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Eu is bonded in a 1-coordinate geometry to two equivalent Au and thirteen In atoms. Both Eu–Au bond lengths are 3.49 Å. There are a spread of Eu–In bond distances ranging from 3.26–3.93 Å. Au is bonded in a 9-coordinate geometry to two equivalent Eu and seven In atoms. There are a spread of Au–In bond distances ranging from 2.79–2.93 Å. There are three inequivalent In sites. In the first In site, In is bonded in a 3-coordinate geometry to three equivalent Eu, three equivalent Au, and one In atom. The In–In bond length is 3.10 Å. In the second In site, In is bonded in a 2-coordinate geometry to three equivalent Eu, one Au, and four equivalent In atoms. All In–In bond lengths are 3.22 Å. In the third In site, In is bonded in a distorted q6 geometry to four equivalent Eu and six In atoms.
