The material described by Ag2Zn2O5 crystallizes in the orthorhombic Pmc2_1 space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to one O(1), two equivalent O(3), and two equivalent O(5) atoms to form AgO5 trigonal bipyramids that share corners with two equivalent Zn(2)O4 tetrahedra, corners with six equivalent Zn(1)O4 tetrahedra, corners with four equivalent Ag(1)O5 trigonal bipyramids, and  a cornercorner with one Ag(2)O4 trigonal pyramid. In the second Ag site, Ag(2) is bonded to one O(1), one O(2), and two equivalent O(4) atoms to form distorted AgO4 trigonal pyramids that share corners with two equivalent Zn(1)O4 tetrahedra, corners with four equivalent Zn(2)O4 tetrahedra,  a cornercorner with one Ag(1)O5 trigonal bipyramid, and corners with two equivalent Ag(2)O4 trigonal pyramids. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to one O(4), one O(5), and two equivalent O(3) atoms to form distorted ZnO4 tetrahedra that share corners with two equivalent Zn(1)O4 tetrahedra, corners with six equivalent Ag(1)O5 trigonal bipyramids, corners with two equivalent Ag(2)O4 trigonal pyramids, and  an edgeedge with one Zn(2)O4 tetrahedra. In the second Zn site, Zn(2) is bonded to one O(4), one O(5), and two equivalent O(2) atoms to form ZnO4 tetrahedra that share corners with two equivalent Zn(2)O4 tetrahedra, corners with two equivalent Ag(1)O5 trigonal bipyramids, corners with four equivalent Ag(2)O4 trigonal pyramids, and  an edgeedge with one Zn(1)O4 tetrahedra. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Ag(1), one Ag(2), and one O(2) atom. In the second O site, O(2) is bonded in a 4-coordinate geometry to one Ag(2), two equivalent Zn(2), and one O(1) atom. In the third O site, O(3) is bonded to two equivalent Ag(1) and two equivalent Zn(1) atoms to form corner-sharing OZn2Ag2 tetrahedra. In the fourth O site, O(4) is bonded to two equivalent Ag(2), one Zn(1), and one Zn(2) atom to form a mixture of edge and corner-sharing OZn2Ag2 tetrahedra. In the fifth O site, O(5) is bonded to two equivalent Ag(1), one Zn(1), and one Zn(2) atom to form a mixture of distorted edge and corner-sharing OZn2Ag2 trigonal pyramids. is represented by the CIF file [CIF]
