The material described by Co4TeO8 is beta indium sulfide-derived structured and crystallizes in the triclinic P-1 space group. There are four inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form CoO6 octahedra that share corners with six equivalent Co(3)O6 octahedra, edges with two equivalent Co(2)O6 octahedra, edges with two equivalent Co(4)O6 octahedra, and edges with two equivalent Te(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 12-21°. In the second Co site, Co(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form CoO6 octahedra that share edges with two equivalent Co(1)O6 octahedra, edges with two equivalent Co(3)O6 octahedra, edges with two equivalent Co(4)O6 octahedra, and edges with two equivalent Te(1)O6 octahedra. In the third Co site, Co(3) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form CoO6 octahedra that share corners with six equivalent Co(1)O6 octahedra, edges with two equivalent Co(2)O6 octahedra, edges with two equivalent Co(4)O6 octahedra, and edges with two equivalent Te(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 12-21°. In the fourth Co site, Co(4) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form CoO6 octahedra that share edges with two equivalent Co(1)O6 octahedra, edges with two equivalent Co(2)O6 octahedra, edges with two equivalent Co(3)O6 octahedra, and edges with two equivalent Te(1)O6 octahedra. Te(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form TeO6 octahedra that share edges with two equivalent Co(1)O6 octahedra, edges with two equivalent Co(2)O6 octahedra, edges with two equivalent Co(3)O6 octahedra, and edges with two equivalent Co(4)O6 octahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one Co(2), one Co(4), and one Te(1) atom. In the second O site, O(2) is bonded in a see-saw-like geometry to one Co(1), one Co(2), one Co(3), and one Co(4) atom. In the third O site, O(3) is bonded in a rectangular see-saw-like geometry to one Co(1), one Co(2), one Co(3), and one Te(1) atom. In the fourth O site, O(4) is bonded in a see-saw-like geometry to one Co(1), one Co(3), one Co(4), and one Te(1) atom. is represented by the CIF file [CIF]
