Li2CoO2 crystallizes in the trigonal P-3m1 space group. Li(1) is bonded to four equivalent O(1) atoms to form LiO4 tetrahedra that share corners with six equivalent Co(1)O6 octahedra, corners with six equivalent Li(1)O4 tetrahedra, edges with three equivalent Co(1)O6 octahedra, and edges with three equivalent Li(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 15-56°. Co(1) is bonded to six equivalent O(1) atoms to form CoO6 octahedra that share corners with twelve equivalent Li(1)O4 tetrahedra, edges with six equivalent Co(1)O6 octahedra, and edges with six equivalent Li(1)O4 tetrahedra. O(1) is bonded in a 7-coordinate geometry to four equivalent Li(1) and three equivalent Co(1) atoms.

The corner-sharing octahedral tilt angles range from 15-56°. There are three shorter (1.92 Å) and one longer (2.08 Å) Li(1)-O(1) bond length. Co(1) is bonded to six equivalent O(1) atoms to form CoO6 octahedra that share corners with twelve equivalent Li(1)O4 tetrahedra, edges with six equivalent Co(1)O6 octahedra, and edges with six equivalent Li(1)O4 tetrahedra. All Co(1)-O(1) bond lengths are 2.19 Å. O(1) is bonded in a 7-coordinate geometry to four equivalent Li(1) and three equivalent Co(1) atoms.
