The material described by LiCoSiO4 crystallizes in the hexagonal P6_3 space group. There are three inequivalent Li sites. In the first Li site, Li(1) is bonded in a trigonal non-coplanar geometry to three equivalent O(2) atoms. In the second Li site, Li(2) is bonded in a 3-coordinate geometry to three equivalent O(4) atoms. In the third Li site, Li(3) is bonded in a trigonal non-coplanar geometry to three equivalent O(1) atoms. Co(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form CoO4 tetrahedra that share corners with four equivalent Si(1)O4 tetrahedra. Si(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form SiO4 tetrahedra that share corners with four equivalent Co(1)O4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Li(3), one Co(1), and one Si(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Li(1), one Co(1), and one Si(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Co(1) and one Si(1) atom. In the fourth O site, O(4) is bonded in a trigonal planar geometry to one Li(2), one Co(1), and one Si(1) atom. is represented by the CIF file [CIF]
