The structure described by Ag2SiO3 crystallizes in the orthorhombic P2_12_12_1 space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 3-coordinate geometry to one O(1) and two equivalent O(2) atoms. In the second Ag site, Ag(2) is bonded in a 3-coordinate geometry to one O(2) and two equivalent O(1) 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 to one Ag(1), two equivalent Ag(2), and one Si(1) atom to form distorted corner-sharing OSiAg3 tetrahedra. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Ag(2), two equivalent Ag(1), and one Si(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to two equivalent Si(1) atoms. is represented by the CIF file [CIF]
