The compound described by Ag8Si(SO2)2 crystallizes in the tetragonal I4_1/amd space group. There are three inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a single-bond geometry to one S(1) atom. In the second Ag site, Ag(2) is bonded in a 3-coordinate geometry to one S(1) and two equivalent O(1) atoms. In the third Ag site, Ag(3) is bonded in a 4-coordinate geometry to two equivalent S(1) and two equivalent O(1) atoms. Si(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. S(1) is bonded in a 6-coordinate geometry to one Ag(1), one Ag(2), and four equivalent Ag(3) atoms. O(1) is bonded in a 4-coordinate geometry to one Ag(2), two equivalent Ag(3), and one Si(1) atom. is represented by the CIF file [CIF]
