LiVSiO4 crystallizes in the monoclinic P2_1/c space group. Li(1) is bonded in a 4-coordinate geometry to one O(1), one O(3), and two equivalent O(4) atoms. V(1) is bonded to one O(4), two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted VO7 pentagonal bipyramids that share corners with three equivalent Si(1)O4 tetrahedra, edges with three equivalent V(1)O7 pentagonal bipyramids, and edges with two 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 three equivalent V(1)O7 pentagonal bipyramids and edges with two equivalent V(1)O7 pentagonal bipyramids. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Li(1), two equivalent V(1), and one Si(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent V(1) and one Si(1) atom. In the third O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to one Li(1), two equivalent V(1), and one Si(1) atom. In the fourth O site, O(4) is bonded in a distorted see-saw-like geometry to two equivalent Li(1), one V(1), and one Si(1) atom.
