Li2Co3SbO8 is Spinel-derived structured and crystallizes in the trigonal R-3m space group. Li(1) is bonded to one O(2) and three equivalent O(1) atoms to form LiO4 tetrahedra that share corners with three equivalent Sb(1)O6 octahedra and corners with nine equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 57-63°. 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)O4 tetrahedra, edges with two equivalent Sb(1)O6 octahedra, and edges with four equivalent Co(1)O6 octahedra. Sb(1) is bonded to six equivalent O(1) atoms to form SbO6 octahedra that share corners with six equivalent Li(1)O4 tetrahedra and 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 rectangular see-saw-like geometry to one Li(1), two equivalent Co(1), and one Sb(1) atom. In the second O site, O(2) is bonded to one Li(1) and three equivalent Co(1) atoms to form distorted corner-sharing OLiCo3 tetrahedra.
