The compound described by LiCo3O4 is Caswellsilverite-like structured and crystallizes in the tetragonal I4/mmm 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 two equivalent Co(2)O6 octahedra, corners with four equivalent Li(1)O6 octahedra, edges with four equivalent Co(2)O6 octahedra, and edges with eight equivalent Co(1)O6 octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent Co sites. In the first Co site, 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 Co(1)O6 octahedra, edges with four equivalent Li(1)O6 octahedra, edges with four equivalent Co(1)O6 octahedra, and edges with four equivalent Co(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 0-8°. In the second Co site, Co(2) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CoO6 octahedra that share corners with two equivalent Li(1)O6 octahedra, corners with four equivalent Co(2)O6 octahedra, edges with four equivalent Li(1)O6 octahedra, and edges with eight equivalent Co(1)O6 octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Li(1), two equivalent Co(1), and two equivalent Co(2) atoms to form OLi2Co4 octahedra that share corners with six equivalent O(1)Li2Co4 octahedra, edges with four equivalent O(1)Li2Co4 octahedra, and edges with eight equivalent O(2)LiCo5 octahedra. The corner-sharing octahedra are not tilted. In the second O site, O(2) is bonded to one Li(1), one Co(2), and four equivalent Co(1) atoms to form OLiCo5 octahedra that share corners with six equivalent O(2)LiCo5 octahedra, edges with four equivalent O(2)LiCo5 octahedra, and edges with eight equivalent O(1)Li2Co4 octahedra. The corner-sharing octahedral tilt angles range from 0-8°. is represented by the CIF file [CIF]
