The material structure described by LiCoSiO4 crystallizes in the triclinic P1 space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a trigonal planar geometry to one O(4), one O(7), and one O(8) atom. In the second Li site, Li(2) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(5) atom. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to one O(3), one O(4), one O(7), and one O(8) atom to form CoO4 tetrahedra that share  a cornercorner with one Si(1)O4 tetrahedra and corners with three equivalent Si(2)O4 tetrahedra. In the second Co site, Co(2) is bonded to one O(1), one O(2), one O(5), and one O(6) atom to form CoO4 tetrahedra that share  a cornercorner with one Si(2)O4 tetrahedra and corners with three equivalent Si(1)O4 tetrahedra. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded to one O(1), one O(2), one O(3), and one O(5) atom to form SiO4 tetrahedra that share  a cornercorner with one Co(1)O4 tetrahedra and corners with three equivalent Co(2)O4 tetrahedra.

There are eight inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Li(2), one Co(2), and one Si(1) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to one Li(2), one Co(2), and one Si(1) atom. In the third O site, O(3) is bonded in a linear 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(1), one Co(1), and one Si(2) atom. In the fifth O site, O(5) is bonded in a trigonal planar geometry to one Li(2), one Co(2), and one Si(1) atom.
