Materials Data on Dy6Zn23 by Materials Project

Abstract

Dy6Zn23 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Dy is bonded in a 12-coordinate geometry to twelve Zn atoms. There are a spread of Dy–Zn bond distances ranging from 3.08–3.22 Å. There are four inequivalent Zn sites. In the first Zn site, Zn is bonded in a 12-coordinate geometry to three equivalent Dy and nine Zn atoms. There are a spread of Zn–Zn bond distances ranging from 2.59–2.82 Å. In the second Zn site, Zn is bonded in a body-centered cubic geometry to eight equivalent Zn atoms. All Zn–Zn bond lengths are 2.69 Å. In the third Zn site, Zn is bonded to four equivalent Dy and eight Zn atoms to form a mixture of face and corner-sharing ZnDy4Zn8 cuboctahedra. All Zn–Zn bond lengths are 2.77 Å. In the fourth Zn site, Zn is bonded in a 10-coordinate geometry to three equivalent Dy and seven Zn atoms.
