Materials Data on NaLi3V4O12 by Materials Project
NaLi3V4O12 is Esseneite-like structured and crystallizes in the monoclinic C2 space group. The structure is three-dimensional. Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.29–2.64 Å. There are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six VO4 tetrahedra and edges with two equivalent LiO6 octahedra. There are a spread of Li–O bond distances ranging from 2.11–2.26 Å. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six VO4 tetrahedra and edges with two equivalent LiO6 octahedra. There are a spread of Li–O bond distances ranging from 2.09–2.30 Å. In the third Li1+ site, Li1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Li–O bond distances ranging from 2.07–2.62 Å. There are two inequivalent V5+ sites. In the first V5+ site, V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share corners with three LiO6 octahedra and corners with two equivalent VO4 tetrahedra. The corner-sharing octahedra tilt angles range from 31–64°. There are a spread of V–O bond distances ranging from 1.67–1.83 Å. In the second V5+ site, V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share corners with three LiO6 octahedra and corners with two equivalent VO4 tetrahedra. The corner-sharing octahedra tilt angles range from 33–60°. There are a spread of V–O bond distances ranging from 1.67–1.83 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one Li1+, and one V5+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to two Li1+ and one V5+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+ and two V5+ atoms. In the fourth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Na1+ and two V5+ atoms. In the fifth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to three Li1+ and one V5+ atom. In the sixth O2- site, O2- is bonded in a 4-coordinate geometry to one Na1+, two Li1+, and one V5+ atom.
