The material described by Ag6SiSO8 crystallizes in the tetragonal I4_1/amd space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(2) atoms. In the second Ag site, Ag(2) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(2) atoms. Si(1) is bonded in a tetrahedral geometry to four equivalent O(2) atoms. S(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Ag(2), two equivalent Ag(1), and one S(1) atom. In the second O site, O(2) is bonded to one Ag(2), two equivalent Ag(1), and one Si(1) atom to form distorted corner-sharing OSiAg3 tetrahedra. is represented by the CIF card [CIF]
