Materials Data on CuAg3S2 by Materials Project

Abstract

Ag3CuS2 crystallizes in the tetragonal I4_1/a space group. The structure is three-dimensional. there are two inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a 2-coordinate geometry to four equivalent S2- atoms. There are a spread of Ag–S bond distances ranging from 2.59–3.21 Å. In the second Ag1+ site, Ag1+ is bonded in a 2-coordinate geometry to six equivalent S2- atoms. There are a spread of Ag–S bond distances ranging from 2.53–3.21 Å. Cu1+ is bonded in a linear geometry to two equivalent S2- atoms. Both Cu–S bond lengths are 2.19 Å. S2- is bonded in a 1-coordinate geometry to seven Ag1+ and one Cu1+ atom.
