The structure described by Li4Co3TeO8 is Caswellsilverite-derived structured and crystallizes in the trigonal R-3m space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded to six equivalent O(2) atoms to form LiO6 octahedra that share corners with six equivalent Te(1)O6 octahedra, edges with six equivalent Li(2)O6 octahedra, and edges with six equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles are 1°. In the second Li site, Li(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form LiO6 octahedra that share corners with six equivalent Co(1)O6 octahedra, edges with two equivalent Li(1)O6 octahedra, edges with two equivalent Te(1)O6 octahedra, edges with four equivalent Li(2)O6 octahedra, and edges with four equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 7-9°. Co(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form CoO6 octahedra that share corners with six equivalent Li(2)O6 octahedra, edges with two equivalent Li(1)O6 octahedra, edges with two equivalent Te(1)O6 octahedra, edges with four equivalent Li(2)O6 octahedra, and edges with four equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 7-9°. Te(1) is bonded to six equivalent O(2) atoms to form TeO6 octahedra that share corners with six equivalent Li(1)O6 octahedra, edges with six equivalent Li(2)O6 octahedra, and edges with six equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles are 1°. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Li(2) and three equivalent Co(1) atoms to form OLi3Co3 octahedra that share corners with six equivalent O(1)Li3Co3 octahedra and edges with twelve equivalent O(2)Li3Co2Te octahedra. The corner-sharing octahedra are not tilted. In the second O site, O(2) is bonded to one Li(1), two equivalent Li(2), two equivalent Co(1), and one Te(1) atom to form OLi3Co2Te octahedra that share corners with six equivalent O(2)Li3Co2Te octahedra, edges with four equivalent O(1)Li3Co3 octahedra, and edges with eight equivalent O(2)Li3Co2Te octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF card [CIF]
