LiCoSiO4 crystallizes in the monoclinic Cc space group. Li(1) is bonded in a rectangular see-saw-like geometry to one O(1), one O(2), one O(3), and one O(4) atom. Co(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form distorted CoO4 trigonal pyramids that share 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 Co(1)O4 trigonal pyramids. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted 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(1), and one Si(1) atom. In the third O site, O(3) is bonded in a distorted T-shaped geometry to one Li(1), one Co(1), and one Si(1) atom. In the fourth O site, O(4) is bonded in a distorted T-shaped geometry to one Li(1), one Co(1), and one Si(1) atom.
