The structure described by LiCoSiO4 crystallizes in the monoclinic P2_1/c space group. 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 three equivalent Co(1)O6 octahedra, corners with three equivalent Co(2)O6 octahedra, and corners with four equivalent Si(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 71-74°. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form CoO6 octahedra that share corners with six equivalent Li(1)O4 tetrahedra, corners with six equivalent Si(1)O4 tetrahedra, and edges with two equivalent Co(2)O6 octahedra. In the second Co site, Co(2) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form CoO6 octahedra that share corners with six equivalent Li(1)O4 tetrahedra, corners with six equivalent Si(1)O4 tetrahedra, and edges with two equivalent Co(1)O6 octahedra. 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 three equivalent Co(1)O6 octahedra, corners with three equivalent Co(2)O6 octahedra, and corners with four equivalent Li(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 48-59°. There are four 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 in a trigonal planar geometry to one Li(1), one Co(2), and one Si(1) atom. In the third O site, O(3) is bonded to one Li(1), one Co(1), one Co(2), and one Si(1) atom to form a mixture of distorted corner and edge-sharing OLiCo2Si tetrahedra. In the fourth O site, O(4) is bonded to one Li(1), one Co(1), one Co(2), and one Si(1) atom to form a mixture of distorted corner and edge-sharing OLiCo2Si tetrahedra. is represented by the CIF card [CIF]
