The material structure described by LiSi2(AgO)8 crystallizes in the tetragonal P-4 space group. Li(1) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted T-shaped geometry to one O(1) and two equivalent O(2) atoms. In the second Ag site, Ag(2) is bonded in a distorted bent 150 degrees geometry to one O(1) and one O(2) atom. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a tetrahedral geometry to four equivalent O(2) atoms. In the second Si site, Si(2) 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 4-coordinate geometry to one Li(1), one Ag(1), one Ag(2), and one Si(2) 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 Crystallographic Information File (CIF) [CIF]
