Title: Materials Data on Yb(AlFe)6 by Materials Project

Abstract

Yb(FeAl)6 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. Yb is bonded in a 8-coordinate geometry to twelve Fe and eight Al atoms. There are four shorter (3.23 Å) and eight longer (3.27 Å) Yb–Fe bond lengths. There are a spread of Yb–Al bond distances ranging from 2.82–2.99 Å. There are two inequivalent Fe sites. In the first Fe site, Fe is bonded to two equivalent Yb, four Fe, and six Al atoms to form a mixture of distorted corner, edge, and face-sharing FeYb2Al6Fe4 cuboctahedra. All Fe–Fe bond lengths are 2.49 Å. There are a spread of Fe–Al bond distances ranging from 2.51–2.59 Å. In the second Fe site, Fe is bonded to two equivalent Yb, four equivalent Fe, and six Al atoms to form a mixture of distorted corner, edge, and face-sharing FeYb2Al6Fe4 cuboctahedra. There are a spread of Fe–Al bond distances ranging from 2.56–2.64 Å. There are three inequivalent Al sites. In the first Al site, Al is bonded in a 10-coordinate geometry to one Yb, six Fe, and three Al atoms. There are one shorter (2.67 Å) and two longer (2.82 Å) Al–Al bond lengths. In the second Al site, Al is bonded inmore » a 7-coordinate geometry to one Yb and six Fe atoms. In the third Al site, Al is bonded in a 12-coordinate geometry to two equivalent Yb, six Fe, and two equivalent Al atoms.« less
