Materials Data on Zn8Ag5 by Materials Project

Abstract

Ag5Zn8 is gamma-brass structured and crystallizes in the cubic I-43m space group. The structure is three-dimensional. there are two inequivalent Ag sites. In the first Ag site, Ag is bonded in a 4-coordinate geometry to three Ag and ten Zn atoms. There are one shorter (2.77 Å) and two longer (2.91 Å) Ag–Ag bond lengths. There are a spread of Ag–Zn bond distances ranging from 2.71–3.01 Å. In the second Ag site, Ag is bonded in a 12-coordinate geometry to three equivalent Ag and nine Zn atoms. There are a spread of Ag–Zn bond distances ranging from 2.67–2.89 Å. There are two inequivalent Zn sites. In the first Zn site, Zn is bonded in a 11-coordinate geometry to six Ag and five Zn atoms. There are four shorter (2.78 Å) and one longer (2.85 Å) Zn–Zn bond lengths. In the second Zn site, Zn is bonded in a 6-coordinate geometry to six Ag and six Zn atoms. All Zn–Zn bond lengths are 2.93 Å.
