The compound described by Li2CoSiO4 is Stannite-like structured and crystallizes in the monoclinic Pc space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form LiO4 tetrahedra that share corners with four equivalent Li(2)O4 tetrahedra, corners with four equivalent Co(1)O4 tetrahedra, and corners with four equivalent Si(1)O4 tetrahedra. In the second Li site, Li(2) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form LiO4 tetrahedra that share corners with four equivalent Li(1)O4 tetrahedra, corners with four equivalent Co(1)O4 tetrahedra, and corners with four equivalent Si(1)O4 tetrahedra. 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 Li(1)O4 tetrahedra, corners with four equivalent Li(2)O4 tetrahedra, and 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 Li(1)O4 tetrahedra, corners with four equivalent Li(2)O4 tetrahedra, and corners with four equivalent Co(1)O4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded to one Li(1), one Li(2), one Co(1), and one Si(1) atom to form corner-sharing OLi2CoSi tetrahedra. In the second O site, O(2) is bonded to one Li(1), one Li(2), one Co(1), and one Si(1) atom to form corner-sharing OLi2CoSi tetrahedra. In the third O site, O(3) is bonded to one Li(1), one Li(2), one Co(1), and one Si(1) atom to form corner-sharing OLi2CoSi tetrahedra. In the fourth O site, O(4) is bonded to one Li(1), one Li(2), one Co(1), and one Si(1) atom to form corner-sharing OLi2CoSi tetrahedra. is represented by the CIF card [CIF]
