Materials Data on ZnCdAg2 by Materials Project

Abstract

Ag2CdZn crystallizes in the orthorhombic Cmm2 space group. The structure is three-dimensional. there are two inequivalent Ag sites. In the first Ag site, Ag is bonded in a 8-coordinate geometry to two equivalent Ag and two equivalent Zn atoms. Both Ag–Ag bond lengths are 2.85 Å. Both Ag–Zn bond lengths are 2.68 Å. In the second Ag site, Ag is bonded in a 10-coordinate geometry to eight Ag and two equivalent Cd atoms. There are four shorter (2.96 Å) and two longer (3.07 Å) Ag–Ag bond lengths. Both Ag–Cd bond lengths are 2.97 Å. Cd is bonded in a 10-coordinate geometry to two equivalent Ag, six equivalent Cd, and two equivalent Zn atoms. There are four shorter (2.96 Å) and two longer (3.07 Å) Cd–Cd bond lengths. Both Cd–Zn bond lengths are 2.87 Å. Zn is bonded in a 8-coordinate geometry to two equivalent Ag and two equivalent Cd atoms.
