Fe3TeO8 is Rutile-derived structured and crystallizes in the hexagonal P6_3mc space group. Fe(1) is bonded to one O(3), one O(4), two equivalent O(1), and two equivalent O(2) atoms to form FeO6 octahedra that share corners with two equivalent Te(1)O6 octahedra,  an edgeedge with one Te(1)O6 octahedra, and edges with four equivalent Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles are 50°. Te(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form TeO6 octahedra that share corners with six equivalent Fe(1)O6 octahedra and edges with three equivalent Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles are 50°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent Fe(1) and one Te(1) atom. In the second O site, O(2) is bonded in a distorted T-shaped geometry to two equivalent Fe(1) and one Te(1) atom. In the third O site, O(3) is bonded in a trigonal non-coplanar geometry to three equivalent Fe(1) atoms. In the fourth O site, O(4) is bonded in a trigonal non-coplanar geometry to three equivalent Fe(1) atoms.
