Materials Data on Ag3SI by Materials Project

Abstract

Ag3SI crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are three inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a 4-coordinate geometry to two equivalent S2- and two equivalent I1- atoms. There are one shorter (2.59 Å) and one longer (2.61 Å) Ag–S bond lengths. There are one shorter (3.03 Å) and one longer (3.09 Å) Ag–I bond lengths. In the second Ag1+ site, Ag1+ is bonded in a 4-coordinate geometry to two equivalent S2- and two equivalent I1- atoms. There are one shorter (2.55 Å) and one longer (2.58 Å) Ag–S bond lengths. There are one shorter (3.09 Å) and one longer (3.26 Å) Ag–I bond lengths. In the third Ag1+ site, Ag1+ is bonded in a 4-coordinate geometry to two equivalent S2- and two equivalent I1- atoms. There are one shorter (2.56 Å) and one longer (2.57 Å) Ag–S bond lengths. There are one shorter (3.07 Å) and one longer (3.19 Å) Ag–I bond lengths. S2- is bonded to six Ag1+ atoms to form distorted corner-sharing SAg6 pentagonal pyramids. I1- is bonded in a 6-coordinate geometry to six Ag1+ atoms.
