Fe5(TeO3)6Cl2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are three inequivalent Fe+2.80+ sites. In the first Fe+2.80+ site, Fe+2.80+ is bonded to six O2- atoms to form edge-sharing FeO6 octahedra. There are a spread of Fe–O bond distances ranging from 1.99–2.06 Å. In the second Fe+2.80+ site, Fe+2.80+ is bonded to six O2- atoms to form a mixture of distorted edge and corner-sharing FeO6 octahedra. The corner-sharing octahedra tilt angles range from 49–57°. There are a spread of Fe–O bond distances ranging from 2.03–2.54 Å. In the third Fe+2.80+ site, Fe+2.80+ is bonded to six O2- atoms to form corner-sharing FeO6 octahedra. The corner-sharing octahedra tilt angles range from 49–57°. There are a spread of Fe–O bond distances ranging from 1.97–2.11 Å. There are three inequivalent Te4+ sites. In the first Te4+ site, Te4+ is bonded in a 4-coordinate geometry to four O2- and two equivalent Cl1- atoms. There are a spread of Te–O bond distances ranging from 1.92–2.47 Å. There are one shorter (3.27 Å) and one longer (3.35 Å) Te–Cl bond lengths. In the second Te4+ site, Te4+ is bonded in a 5-coordinate geometry to five O2- and one Cl1- atom. There are a spread of Te–O bond distances ranging from 1.91–2.61 Å. The Te–Cl bond length is 3.33 Å. In the third Te4+ site, Te4+ is bonded in a 3-coordinate geometry to three O2- and three equivalent Cl1- atoms. There is two shorter (1.91 Å) and one longer (1.95 Å) Te–O bond length. There are a spread of Te–Cl bond distances ranging from 3.01–3.41 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two Fe+2.80+, one Te4+, and one Cl1- atom. The O–Cl bond length is 3.42 Å. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two Fe+2.80+ and one Te4+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Fe+2.80+, one Te4+, and one Cl1- atom. The O–Cl bond length is 3.31 Å. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Fe+2.80+ and two equivalent Te4+ atoms. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Fe+2.80+ and one Te4+ atom. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to one Fe+2.80+, two Te4+, and one Cl1- atom. The O–Cl bond length is 3.32 Å. In the seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Fe+2.80+, one Te4+, and one Cl1- atom. The O–Cl bond length is 3.30 Å. In the eighth O2- site, O2- is bonded in a 2-coordinate geometry to one Fe+2.80+, two Te4+, and two equivalent Cl1- atoms. There are one shorter (3.24 Å) and one longer (3.57 Å) O–Cl bond lengths. In the ninth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Fe+2.80+ and one Te4+ atom. Cl1- is bonded in a 6-coordinate geometry to six Te4+, six O2-, and two equivalent Cl1- atoms. There are one shorter (3.55 Å) and one longer (3.79 Å) Cl–Cl bond lengths.
