Materials Data on LiVSiO4 by Materials Project
LiVSiO4 is Hausmannite-derived structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with four equivalent VO6 octahedra, corners with two equivalent SiO4 tetrahedra, edges with two equivalent LiO6 octahedra, edges with two equivalent VO6 octahedra, and edges with two equivalent SiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 57–64°. There are a spread of Li–O bond distances ranging from 2.08–2.27 Å. V3+ is bonded to six O2- atoms to form VO6 octahedra that share corners with four equivalent LiO6 octahedra, corners with four equivalent VO6 octahedra, corners with four equivalent SiO4 tetrahedra, edges with two equivalent LiO6 octahedra, and an edgeedge with one SiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 48–64°. There are a spread of V–O bond distances ranging from 2.01–2.14 Å. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with two equivalent LiO6 octahedra, corners with four equivalent VO6 octahedra, an edgeedge with one VO6 octahedra, and edges with two equivalent LiO6 octahedra. The corner-sharing octahedra tilt angles range from 51–60°. There are a spread of Si–O bond distances ranging from 1.61–1.69 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two equivalent Li1+, one V3+, and one Si4+ atom. In the second O2- site, O2- is bonded in a rectangular see-saw-like geometry to two equivalent Li1+, one V3+, and one Si4+ atom. In the third O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Li1+, two equivalent V3+, and one Si4+ atom.
