The structure described by Fe5(TeO3)6Cl2 crystallizes in the triclinic P-1 space group. There are three inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to one O(1), one O(9), two equivalent O(3), and two equivalent O(7) atoms to form FeO6 octahedra that share corners with three equivalent Te(2)O5 square pyramids,  an edgeedge with one Fe(2)O6 octahedra, and edges with two equivalent Fe(1)O6 octahedra. In the second Fe site, Fe(2) is bonded to one O(1), one O(2), one O(4), one O(5), one O(6), and one O(9) atom to form distorted FeO6 octahedra that share corners with two equivalent Fe(3)O6 octahedra, corners with four equivalent Te(2)O5 square pyramids, and  an edgeedge with one Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 49-57°. In the third Fe site, Fe(3) is bonded to two equivalent O(2), two equivalent O(5), and two equivalent O(8) atoms to form corner-sharing FeO6 octahedra. The corner-sharing octahedral tilt angles range from 49-57°. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded in a distorted see-saw-like geometry to one O(1), one O(2), one O(7), and one O(8) atom. In the second Te site, Te(2) is bonded to one O(3), one O(6), one O(9), and two equivalent O(4) atoms to form distorted TeO5 square pyramids that share corners with three equivalent Fe(1)O6 octahedra, corners with four equivalent Fe(2)O6 octahedra, and  an edgeedge with one Te(2)O5 square pyramid. The corner-sharing octahedral tilt angles range from 40-57°. In the third Te site, Te(3) is bonded in a 3-coordinate geometry to one O(5), one O(6), one O(8), and one Cl(1) atom. There are nine inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Fe(1), one Fe(2), and one Te(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Fe(2), one Fe(3), and one Te(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to two equivalent Fe(1) and one Te(2) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Fe(2) and two equivalent Te(2) atoms. In the fifth O site, O(5) is bonded in a distorted trigonal planar geometry to one Fe(2), one Fe(3), and one Te(3) atom. In the sixth O site, O(6) is bonded in a 3-coordinate geometry to one Fe(2), one Te(2), and one Te(3) atom. In the seventh O site, O(7) is bonded in a distorted trigonal planar geometry to two equivalent Fe(1) and one Te(1) atom. In the eighth O site, O(8) is bonded in a 3-coordinate geometry to one Fe(3), one Te(1), and one Te(3) atom. In the ninth O site, O(9) is bonded in a distorted trigonal planar geometry to one Fe(1), one Fe(2), and one Te(2) atom.
