Co3TeO8 is trigonal omega-derived structured and crystallizes in the trigonal R-3m space group. Co(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CoO6 octahedra that share edges with two equivalent Te(1)O6 octahedra and edges with four equivalent Co(1)O6 octahedra. Te(1) is bonded to six equivalent O(1) atoms to form TeO6 octahedra that share edges with six equivalent Co(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to two equivalent Co(1) and one Te(1) atom. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Co(1) atoms.

Co(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CoO6 octahedra that share edges with two equivalent Te(1)O6 octahedra and edges with four equivalent Co(1)O6 octahedra. Both Co(1)-O(2) bond lengths are 1.87 Å. All Co(1)-O(1) bond lengths are 1.94 Å. Te(1) is bonded to six equivalent O(1) atoms to form TeO6 octahedra that share edges with six equivalent Co(1)O6 octahedra. All Te(1)-O(1) bond lengths are 1.99 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to two equivalent Co(1) and one Te(1) atom. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Co(1) atoms.
