The crystal structure described by Li2Co(SiO3)2 crystallizes in the orthorhombic Fdd2 space group. Li(1) is bonded to one O(1), one O(3), and two equivalent O(2) atoms to form LiO4 tetrahedra that share corners with two equivalent Li(1)O4 tetrahedra, corners with three equivalent Co(1)O4 tetrahedra, and corners with five 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 six equivalent Li(1)O4 tetrahedra. Si(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form SiO4 tetrahedra that share corners with two equivalent Co(1)O4 tetrahedra, corners with two equivalent Si(1)O4 tetrahedra, and corners with five equivalent Li(1)O4 tetrahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Li(1), one Co(1), and one Si(1) atom. 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. In the third O site, O(3) is bonded in a trigonal planar geometry to one Li(1) and two equivalent Si(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
