Fe2TeO6 is Hydrophilite-derived structured and crystallizes in the tetragonal P4_2/mnm space group. Fe(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form FeO6 octahedra that share corners with four equivalent Fe(1)O6 octahedra, corners with four equivalent Te(1)O6 octahedra,  an edgeedge with one Fe(1)O6 octahedra, and  an edgeedge with one Te(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 50-52°. Te(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form TeO6 octahedra that share corners with eight equivalent Fe(1)O6 octahedra and edges with two equivalent Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 51-52°. There are two inequivalent O sites. In the first O site, O(2) is bonded in a trigonal planar geometry to two equivalent Fe(1) and one Te(1) atom. In the second O site, O(1) is bonded in a trigonal planar geometry to two equivalent Fe(1) and one Te(1) atom.

The corner-sharing octahedral tilt angles range from 50-52°. Both Fe(1)-O(2) bond lengths are 1.91 Å. There are two shorter (1.89 Å) and two longer (1.92 Å) Fe(1)-O(1) bond lengths. Te(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form TeO6 octahedra that share corners with eight equivalent Fe(1)O6 octahedra and edges with two equivalent Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 51-52°. Both Te(1)-O(2) bond lengths are 1.93 Å. All Te(1)-O(1) bond lengths are 1.94 Å. There are two inequivalent O sites. In the first O site, O(2) is bonded in a trigonal planar geometry to two equivalent Fe(1) and one Te(1) atom. In the second O site, O(1) is bonded in a trigonal planar geometry to two equivalent Fe(1) and one Te(1) atom.
