The compound described by LiVSiO4 crystallizes in the orthorhombic Pnma space group. Li(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form LiO4 tetrahedra that share corners with six equivalent V(1)O6 octahedra and corners with four equivalent Si(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 71-74°. V(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form VO6 octahedra that share corners with six equivalent Li(1)O4 tetrahedra, corners with six equivalent Si(1)O4 tetrahedra, and edges with two equivalent V(1)O6 octahedra. Si(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form SiO4 tetrahedra that share corners with six equivalent V(1)O6 octahedra and corners with four equivalent Li(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 50-56°. There are three inequivalent O sites. In the first O site, O(1) is bonded to one Li(1), two equivalent V(1), and one Si(1) atom to form a mixture of distorted edge and corner-sharing OLiV2Si tetrahedra. In the second O site, O(2) is bonded to one Li(1), two equivalent V(1), and one Si(1) atom to form a mixture of distorted edge and corner-sharing OLiV2Si tetrahedra. In the third O site, O(3) is bonded in a trigonal planar geometry to one Li(1), one V(1), and one Si(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
