The crystal structure described by Li3CrCo3O8 crystallizes in the trigonal R-3m space group. Li(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form LiO6 octahedra that share corners with six equivalent Co(1)O6 octahedra, edges with two equivalent Cr(1)O6 octahedra, edges with four equivalent Li(1)O6 octahedra, and edges with four equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles are 8°. Cr(1) is bonded to six equivalent O(1) atoms to form CrO6 octahedra that share edges with six equivalent Li(1)O6 octahedra and edges with six equivalent Co(1)O6 octahedra. Co(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CoO6 octahedra that share corners with six equivalent Li(1)O6 octahedra, edges with two equivalent Cr(1)O6 octahedra, edges with four equivalent Li(1)O6 octahedra, and edges with four equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles are 8°. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Li(1), one Cr(1), and two equivalent Co(1) atoms to form OLi2CrCo2 square pyramids that share corners with nine equivalent O(1)Li2CrCo2 square pyramids, edges with four equivalent O(2)Li3Co3 octahedra, and edges with four equivalent O(1)Li2CrCo2 square pyramids. In the second O site, O(2) is bonded to three equivalent Li(1) and three equivalent Co(1) atoms to form OLi3Co3 octahedra that share corners with six equivalent O(2)Li3Co3 octahedra and edges with twelve equivalent O(1)Li2CrCo2 square pyramids. The corner-sharing octahedra are not tilted. is represented by the CIF file [CIF]
