The material described by LiCoSiO4 is Spinel-derived structured and crystallizes in the tetragonal P4_322 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 Si(1)O4 tetrahedra, edges with two equivalent Li(1)O6 octahedra, and edges with four equivalent Co(1)O6 octahedra. 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 Si(1)O4 tetrahedra, edges with two equivalent Co(1)O6 octahedra, and edges with four equivalent Li(1)O6 octahedra. Si(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form SiO4 tetrahedra that share corners with six equivalent Li(1)O6 octahedra and corners with six equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 51-54°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like geometry to two equivalent Li(1), one Co(1), and one Si(1) atom. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to one Li(1), two equivalent Co(1), and one Si(1) atom. is represented by the CIF card [CIF]
