The crystal structure described by Cu7Te6(O9F)2 crystallizes in the triclinic P-1 space group. There are four inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a square co-planar geometry to two equivalent O(2) and two equivalent O(3) atoms. In the second Cu site, Cu(2) is bonded to one O(1), one O(3), one O(4), one O(8), and one O(9) atom to form distorted corner-sharing CuO5 trigonal bipyramids. In the third Cu site, Cu(3) is bonded in a 4-coordinate geometry to one O(1), one O(5), one O(8), and two equivalent O(7) atoms. In the fourth Cu site, Cu(4) is bonded to one O(4), one O(8), two equivalent O(6), and one F(1) atom to form CuO4F trigonal bipyramids that share corners with two equivalent Cu(2)O5 trigonal bipyramids and  an edgeedge with one Cu(4)O4F trigonal bipyramid. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(3), one O(5), and one O(7) atom. In the second Te site, Te(2) is bonded in a 3-coordinate geometry to one O(5), one O(6), and one O(8) atom. In the third Te site, Te(3) is bonded in a distorted trigonal non-coplanar geometry to one O(2), one O(4), and one O(9) atom. There are nine inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Cu(2), one Cu(3), and one Te(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Cu(1), one Te(1), and one Te(3) atom.

In the fourth O site, O(4) is bonded in a trigonal planar geometry to one Cu(2), one Cu(4), and one Te(3) atom. In the fifth O site, O(5) is bonded in a 2-coordinate geometry to one Cu(3), one Te(1), and one Te(2) atom. In the sixth O site, O(6) is bonded in a 3-coordinate geometry to two equivalent Cu(4) and one Te(2) atom. In the seventh O site, O(7) is bonded in a trigonal non-coplanar geometry to two equivalent Cu(3) and one Te(1) atom. In the eighth O site, O(8) is bonded in a distorted tetrahedral geometry to one Cu(2), one Cu(3), one Cu(4), and one Te(2) atom. In the ninth O site, O(9) is bonded in a bent 120 degrees geometry to one Cu(2) and one Te(3) atom. F(1) is bonded in a single-bond geometry to one Cu(4) atom. is represented by the CIF card [CIF]
