The crystal structure described by Li2VSiO4 crystallizes in the monoclinic Pc space group. There are two inequivalent Li sites. In the first Li site, 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 four equivalent Li(2)O4 tetrahedra and corners with four equivalent Si(1)O4 tetrahedra. In the second Li site, Li(2) 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 four equivalent Li(1)O4 tetrahedra and corners with four equivalent Si(1)O4 tetrahedra. V(1) is bonded in a 4-coordinate geometry to one O(1), one O(2), one O(3), and one O(4) atom. 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 Li(1)O4 tetrahedra and corners with four equivalent Li(2)O4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one Li(1), one Li(2), one V(1), and one Si(1) atom. In the second O site, O(2) is bonded to one Li(1), one Li(2), one V(1), and one Si(1) atom to form distorted corner-sharing OLi2VSi tetrahedra. In the third O site, O(3) is bonded to one Li(1), one Li(2), one V(1), and one Si(1) atom to form corner-sharing OLi2VSi tetrahedra. In the fourth O site, O(4) is bonded to one Li(1), one Li(2), one V(1), and one Si(1) atom to form distorted corner-sharing OLi2VSi trigonal pyramids. is represented by the CIF file [CIF]
