Materials Data on EuIn4Ir by Materials Project

Abstract

EuIrIn4 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Eu is bonded in a 5-coordinate geometry to two equivalent Ir and thirteen In atoms. Both Eu–Ir bond lengths are 3.47 Å. There are a spread of Eu–In bond distances ranging from 3.33–3.84 Å. Ir is bonded in a 7-coordinate geometry to two equivalent Eu and seven In atoms. There are a spread of Ir–In bond distances ranging from 2.69–2.82 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 Ir, and one In atom. The In–In bond length is 3.20 Å. In the second In site, In is bonded in a 1-coordinate geometry to three equivalent Eu, one Ir, and four equivalent In atoms. All In–In bond lengths are 3.16 Å. In the third In site, In is bonded in a distorted q6 geometry to four equivalent Eu and six In atoms.
