Title: Materials Data on Eu5Mg by Materials Project

Abstract

MgEu5 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. Mg is bonded in a distorted q6 geometry to ten Eu atoms. There are a spread of Mg–Eu bond distances ranging from 3.62–3.82 Å. There are five inequivalent Eu sites. In the first Eu site, Eu is bonded to twelve Eu atoms to form EuEu12 cuboctahedra that share corners with eighteen EuEu12 cuboctahedra, edges with ten EuEu10Mg2 cuboctahedra, and faces with eighteen EuEu12 cuboctahedra. There are a spread of Eu–Eu bond distances ranging from 3.81–4.01 Å. In the second Eu site, Eu is bonded to four equivalent Mg and eight Eu atoms to form a mixture of distorted face, edge, and corner-sharing EuEu8Mg4 cuboctahedra. There are a spread of Eu–Eu bond distances ranging from 3.67–4.01 Å. In the third Eu site, Eu is bonded to two equivalent Mg and ten Eu atoms to form a mixture of face, edge, and corner-sharing EuEu10Mg2 cuboctahedra. There are four shorter (3.76 Å) and two longer (4.01 Å) Eu–Eu bond lengths. In the fourth Eu site, Eu is bonded to two equivalent Mg and ten Eu atoms to form distorted EuEu10Mg2 cuboctahedra that share corners with twelve EuEu10Mg2 cuboctahedra, edges with fifteenmore » EuEu12 cuboctahedra, and faces with eighteen EuEu12 cuboctahedra. There are two shorter (4.01 Å) and two longer (4.10 Å) Eu–Eu bond lengths. In the fifth Eu site, Eu is bonded to two equivalent Mg and ten Eu atoms to form distorted EuEu10Mg2 cuboctahedra that share corners with twelve EuEu10Mg2 cuboctahedra, edges with fifteen EuEu8Mg4 cuboctahedra, and faces with eighteen EuEu12 cuboctahedra. Both Eu–Eu bond lengths are 4.01 Å.« less
