The compound described by Ag2ZnGeO4 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 Ge(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 Ge(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 Ge(1)O4 tetrahedra. Ge(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form GeO4 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 to one Ag(1), one Ag(2), one Zn(1), and one Ge(1) atom to form distorted corner-sharing OZnAg2Ge trigonal pyramids. 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 Ge(1) atom. In the third O site, O(3) is bonded to one Ag(1), one Ag(2), one Zn(1), and one Ge(1) atom to form distorted corner-sharing OZnAg2Ge tetrahedra. In the fourth O site, O(4) is bonded to one Ag(1), one Ag(2), one Zn(1), and one Ge(1) atom to form distorted corner-sharing OZnAg2Ge tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
