The crystal structure described by Ag2ZnSiO4 crystallizes in the monoclinic Pc space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form AgO4 tetrahedra that share corners with four equivalent Ag(2)O4 tetrahedra, corners with four equivalent Zn(1)O4 tetrahedra, and corners with four equivalent Si(1)O4 tetrahedra. In the second Ag site, Ag(2) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form AgO4 tetrahedra that share corners with four equivalent Ag(1)O4 tetrahedra, corners with four equivalent Zn(1)O4 tetrahedra, and corners with four equivalent Si(1)O4 tetrahedra. Zn(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form ZnO4 tetrahedra that share corners with four equivalent Ag(1)O4 tetrahedra, corners with four equivalent Ag(2)O4 tetrahedra, and corners with four equivalent Si(1)O4 tetrahedra. Si(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form SiO4 tetrahedra that share corners with four equivalent Ag(1)O4 tetrahedra, corners with four equivalent Ag(2)O4 tetrahedra, and corners with four equivalent Zn(1)O4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Ag(1), one Ag(2), one Zn(1), and one Si(1) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Ag(1), one Ag(2), one Zn(1), and one Si(1) atom. In the third O site, O(3) is bonded in a 4-coordinate geometry to one Ag(1), one Ag(2), one Zn(1), and one Si(1) atom. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one Ag(1), one Ag(2), one Zn(1), and one Si(1) atom. is represented by the CIF card [CIF]
