Materials Data on LuAlCo by Materials Project
Abstract
LuCoAl crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are two inequivalent Lu sites. In the first Lu site, Lu is bonded in a 12-coordinate geometry to three equivalent Lu, five Co, and seven Al atoms. There are two shorter (3.21 Å) and one longer (3.22 Å) Lu–Lu bond lengths. There are a spread of Lu–Co bond distances ranging from 2.85–3.16 Å. There are a spread of Lu–Al bond distances ranging from 3.10–3.14 Å. In the second Lu site, Lu is bonded in a 12-coordinate geometry to four Lu, seven Co, and five Al atoms. The Lu–Lu bond length is 2.92 Å. There are a spread of Lu–Co bond distances ranging from 2.97–3.08 Å. There are a spread of Lu–Al bond distances ranging from 2.98–3.13 Å. There are three inequivalent Co sites. In the first Co site, Co is bonded to six Lu and six Al atoms to form CoLu6Al6 cuboctahedra that share corners with four equivalent CoLu6Al6 cuboctahedra, corners with four equivalent AlLu6Al2Co4 cuboctahedra, edges with two equivalent CoLu6Al6 cuboctahedra, and faces with fourteen AlLu6Al2Co4 cuboctahedra. There are a spread of Co–Al bond distances ranging from 2.59–2.70 Å. In the second Co site, Co ismore »
