Materials Data on Eu(In2Au)2 by Materials Project
Eu(AuIn2)2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Eu is bonded in a 11-coordinate geometry to four Au and ten In atoms. There are two shorter (3.46 Å) and two longer (3.53 Å) Eu–Au bond lengths. There are a spread of Eu–In bond distances ranging from 3.35–3.76 Å. There are two inequivalent Au sites. In the first Au site, Au is bonded in a 7-coordinate geometry to two equivalent Eu and seven In atoms. There are a spread of Au–In bond distances ranging from 2.85–2.89 Å. In the second Au site, 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 2.83–3.05 Å. There are four inequivalent In sites. In the first In site, In is bonded to one Eu and four Au atoms to form a mixture of distorted corner and edge-sharing InEuAu4 tetrahedra. In the second In site, In is bonded in a 3-coordinate geometry to three equivalent Eu and three equivalent Au atoms. In the third In site, In is bonded in a 3-coordinate geometry to three equivalent Eu and three equivalent Au atoms. In the fourth In site, In is bonded in a 4-coordinate geometry to three equivalent Eu and four Au atoms.
