The compound described by Li2CoSiO4 is Stannite structured and crystallizes in the monoclinic C2 space group. Li(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms 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 two equivalent O(1) and two equivalent O(2) atoms to form CoO4 tetrahedra that share corners with four equivalent Si(1)O4 tetrahedra and corners with eight equivalent Li(1)O4 tetrahedra. Si(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form SiO4 tetrahedra that share corners with four equivalent Co(1)O4 tetrahedra and corners with eight equivalent Li(1)O4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Li(1), one Co(1), and one Si(1) atom to form corner-sharing OLi2CoSi tetrahedra. In the second O site, O(2) is bonded to two equivalent Li(1), one Co(1), and one Si(1) atom to form corner-sharing OLi2CoSi tetrahedra. is represented by the CIF card [CIF]
