In the third Te site, Te(3) is bonded to one O(10), one O(11), one O(4), one O(5), one O(8), and one O(9) atom to form TeO6 octahedra that share corners with three equivalent Te(1)O6 octahedra,  a cornercorner with one Te(2)O5 square pyramid, and corners with two equivalent Te(4)O5 square pyramids. The corner-sharing octahedral tilt angles range from 38-42°. In the fourth Te site, Te(4) is bonded to one O(1), one O(3), one O(4), one O(5), and one O(7) atom to form TeO5 square pyramids that share corners with two equivalent Te(1)O6 octahedra, corners with two equivalent Te(3)O6 octahedra, and  a cornercorner with one Te(2)O5 square pyramid. The corner-sharing octahedral tilt angles range from 41-52°. There are eleven inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Ag(2), one Te(2), and one Te(4) atom.

In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one Ag(1), one Ag(2), one Te(3), and one Te(4) atom. In the fifth O site, O(5) is bonded in a distorted trigonal non-coplanar geometry to one Ag(1), one Te(3), and one Te(4) atom. In the sixth O site, O(6) is bonded in a 4-coordinate geometry to one Ag(1), one Ag(2), and two equivalent Te(2) atoms. In the seventh O site, O(7) is bonded in a distorted trigonal non-coplanar geometry to one Ag(2), one Te(1), and one Te(4) atom. In the eighth O site, O(8) is bonded in a 4-coordinate geometry to two equivalent Ag(2), one Te(2), and one Te(3) atom.
