Ag2Te2O7 crystallizes in the orthorhombic Imma space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 6-coordinate geometry to two equivalent O(3) and four equivalent O(1) atoms. In the second Ag site, Ag(2) is bonded in a distorted square co-planar geometry to four equivalent O(1) and four equivalent O(3) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded to two equivalent O(3) and four equivalent O(1) atoms to form corner-sharing TeO6 octahedra. The corner-sharing octahedral tilt angles are 41°. In the second Te site, Te(2) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form corner-sharing TeO6 octahedra. The corner-sharing octahedral tilt angles are 41°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one Ag(1), one Ag(2), one Te(1), and one Te(2) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Te(2) atoms. In the third O site, O(3) is bonded to one Ag(1), two equivalent Ag(2), and one Te(1) atom to form a mixture of distorted corner and edge-sharing OAg3Te tetrahedra.
