Materials Data on Ag(AuS)2 by Materials Project
Ag(AuS)2 crystallizes in the monoclinic Pc space group. The structure is three-dimensional. there are two inequivalent Au+1.50+ sites. In the first Au+1.50+ site, Au+1.50+ is bonded in a distorted linear geometry to two S2- atoms. There are one shorter (2.32 Å) and one longer (2.34 Å) Au–S bond lengths. In the second Au+1.50+ site, Au+1.50+ is bonded in a linear geometry to two equivalent S2- atoms. Both Au–S bond lengths are 2.33 Å. Ag1+ is bonded in a 4-coordinate geometry to four S2- atoms. There are a spread of Ag–S bond distances ranging from 2.50–2.97 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded to three Au+1.50+ and one Ag1+ atom to form distorted corner-sharing SAgAu3 tetrahedra. In the second S2- site, S2- is bonded in a 4-coordinate geometry to one Au+1.50+ and three equivalent Ag1+ atoms.
