Materials Data on Yb5Ag3 by Materials Project

Abstract

Yb5Ag3 crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. there are two inequivalent Yb sites. In the first Yb site, Yb is bonded to five Ag atoms to form a mixture of distorted edge, corner, and face-sharing YbAg5 trigonal bipyramids. There are a spread of Yb–Ag bond distances ranging from 3.11–3.32 Å. In the second Yb site, Yb is bonded in a distorted square co-planar geometry to six Ag atoms. There are four shorter (3.10 Å) and two longer (3.68 Å) Yb–Ag bond lengths. There are two inequivalent Ag sites. In the first Ag site, Ag is bonded in a 10-coordinate geometry to ten Yb atoms. In the second Ag site, Ag is bonded in a 9-coordinate geometry to eight Yb and one Ag atom. The Ag–Ag bond length is 2.89 Å.
