Materials Data on Yb4Al23Ni6 by Materials Project
Abstract
Yb4Ni6Al23 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Yb sites. In the first Yb site, Yb is bonded in a 9-coordinate geometry to two equivalent Ni and thirteen Al atoms. Both Yb–Ni bond lengths are 3.23 Å. There are a spread of Yb–Al bond distances ranging from 3.02–3.33 Å. In the second Yb site, Yb is bonded in a 2-coordinate geometry to two equivalent Ni and thirteen Al atoms. Both Yb–Ni bond lengths are 3.18 Å. There are a spread of Yb–Al bond distances ranging from 3.04–3.29 Å. There are three inequivalent Ni sites. In the first Ni site, Ni is bonded in a 7-coordinate geometry to two equivalent Yb and seven Al atoms. There are a spread of Ni–Al bond distances ranging from 2.37–2.52 Å. In the second Ni site, Ni is bonded in a 9-coordinate geometry to nine Al atoms. There are a spread of Ni–Al bond distances ranging from 2.40–2.77 Å. In the third Ni site, Ni is bonded in a 10-coordinate geometry to two equivalent Yb and eight Al atoms. There are a spread of Ni–Al bond distances ranging from 2.39–2.55 Å. There are twelve inequivalent Al sites.more »
