ZnTe6O13 crystallizes in the trigonal R-3 space group. Zn(1) is bonded to three equivalent O(4) and three equivalent O(5) atoms to form ZnO6 octahedra that share corners with six equivalent Te(2)O5 square pyramids. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a distorted rectangular see-saw-like geometry to one O(2), one O(3), and two equivalent O(5) atoms. In the second Te site, Te(2) is bonded to one O(3), two equivalent O(1), and two equivalent O(4) atoms to form distorted TeO5 square pyramids that share corners with two equivalent Zn(1)O6 octahedra, corners with two equivalent Te(2)O5 square pyramids, and  an edgeedge with one Te(2)O5 square pyramid. The corner-sharing octahedral tilt angles range from 49-68°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to two equivalent Te(2) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to three equivalent Te(1) atoms. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Te(1) and one Te(2) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Zn(1) and two equivalent Te(2) atoms. In the fifth O site, O(5) is bonded in a trigonal planar geometry to one Zn(1) and two equivalent Te(1) atoms.
