The crystal structure described by Fe2(TeO4)3 crystallizes in the triclinic P-1 space group. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to one O(10), one O(2), one O(6), one O(7), and two equivalent O(9) atoms to form distorted FeO6 octahedra that share  a cornercorner with one Te(3)O4 tetrahedra, corners with two equivalent Te(2)O4 tetrahedra, corners with three equivalent Te(1)O4 tetrahedra, and  an edgeedge with one Fe(1)O6 octahedra. In the second Fe site, Fe(2) is bonded to one O(3), one O(4), one O(5), one O(8), and two equivalent O(1) atoms to form FeO6 octahedra that share corners with two equivalent Te(1)O4 tetrahedra, corners with two equivalent Te(2)O4 tetrahedra, corners with two equivalent Te(3)O4 tetrahedra, and  an edgeedge with one Fe(2)O6 octahedra. There are three inequivalent Te sites. In the first Te site, Te(1) is bonded to one O(1), one O(12), one O(6), and one O(9) atom to form TeO4 tetrahedra that share corners with two equivalent Fe(2)O6 octahedra and corners with three equivalent Fe(1)O6 octahedra.

The corner-sharing octahedral tilt angles range from 22-44°. There are twelve inequivalent O sites. In the first O site, O(12) is bonded in a single-bond geometry to one Te(1) atom. In the second O site, O(1) is bonded in a trigonal planar geometry to two equivalent Fe(2) and one Te(1) atom. In the third O site, O(2) is bonded in a bent 150 degrees geometry to one Fe(1) and one Te(3) atom.
