Co2TeSO8 crystallizes in the orthorhombic Pbcm space group. Co(1) is bonded to one O(1), one O(3), one O(4), one O(6), and two equivalent O(5) atoms to form distorted CoO6 octahedra that share  a cornercorner with one Co(1)O6 octahedra, corners with two equivalent S(1)O4 tetrahedra, and edges with two equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles are 33°. Te(1) is bonded in a distorted trigonal non-coplanar geometry to one O(1) and two equivalent O(5) atoms. S(1) is bonded to one O(2), one O(3), and two equivalent O(6) atoms to form SO4 tetrahedra that share corners with four equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 51-52°. There are six inequivalent O sites. In the first O site, O(5) is bonded in a trigonal planar geometry to two equivalent Co(1) and one Te(1) atom. In the second O site, O(6) is bonded in a bent 120 degrees geometry to one Co(1) and one S(1) atom. In the third O site, O(1) is bonded in a trigonal planar geometry to two equivalent Co(1) and one Te(1) atom. In the fourth O site, O(2) is bonded in a single-bond geometry to one S(1) atom. In the fifth O site, O(3) is bonded in a distorted trigonal planar geometry to two equivalent Co(1) and one S(1) atom. In the sixth O site, O(4) is bonded in a bent 150 degrees geometry to two equivalent Co(1) atoms.
