Materials Data on SiAg6SO8 by Materials Project
Ag6SiSO8 crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. there are two inequivalent Ag+2.33+ sites. In the first Ag+2.33+ site, Ag+2.33+ is bonded in a distorted see-saw-like geometry to four O2- atoms. There are two shorter (2.22 Å) and two longer (2.58 Å) Ag–O bond lengths. In the second Ag+2.33+ site, Ag+2.33+ is bonded in a 4-coordinate geometry to four O2- atoms. There are two shorter (2.46 Å) and two longer (2.56 Å) Ag–O bond lengths. Si4+ is bonded in a tetrahedral geometry to four equivalent O2- atoms. All Si–O bond lengths are 1.66 Å. S2- is bonded in a tetrahedral geometry to four equivalent O2- atoms. All S–O bond lengths are 1.50 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three Ag+2.33+ and one S2- atom. In the second O2- site, O2- is bonded to three Ag+2.33+ and one Si4+ atom to form distorted corner-sharing OSiAg3 tetrahedra.
