The compound described by Ag2Si2O5 crystallizes in the orthorhombic Pbcn space group. Ag(1) is bonded in a 5-coordinate geometry to one O(3) and four equivalent O(2) atoms. Si(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form corner-sharing SiO4 tetrahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent Si(1) atoms. In the second O site, O(2) is bonded in a 1-coordinate geometry to four equivalent Ag(1) and one Si(1) atom. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Ag(1) and two equivalent Si(1) atoms. is represented by the CIF file [CIF]
