The material structure described by LiSi2(AgO)8 crystallizes in the monoclinic P2 space group. Li(1) is bonded in a distorted bent 120 degrees geometry to two equivalent O(1) atoms. There are four inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 3-coordinate geometry to one O(1), one O(2), and one O(4) atom. In the second Ag site, Ag(2) is bonded in a 2-coordinate geometry to one O(1), one O(3), and one O(4) atom. In the third Ag site, Ag(3) is bonded in a 3-coordinate geometry to one O(1), one O(2), and one O(3) atom. In the fourth Ag site, Ag(4) is bonded in a 3-coordinate geometry to one O(2), one O(3), and one O(4) atom. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a tetrahedral geometry to two equivalent O(2) and two equivalent O(4) atoms. In the second Si site, Si(2) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(3) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to one Li(1), one Ag(1), one Ag(2), one Ag(3), and one Si(2) atom. In the second O site, O(2) is bonded in a 1-coordinate geometry to one Ag(1), one Ag(3), one Ag(4), and one Si(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Ag(2), one Ag(3), one Ag(4), and one Si(2) atom. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one Ag(1), one Ag(2), one Ag(4), and one Si(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
