Na3LiV4O12 is Esseneite-like structured and crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are three inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.38–2.63 Å. In the second Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.38–2.60 Å. In the third Na1+ site, Na1+ is bonded to six O2- atoms to form NaO6 octahedra that share corners with six VO4 tetrahedra and edges with two equivalent LiO6 octahedra. There are a spread of Na–O bond distances ranging from 2.31–2.38 Å. Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six VO4 tetrahedra and edges with two equivalent NaO6 octahedra. There are a spread of Li–O bond distances ranging from 2.21–2.33 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 a cornercorner with one NaO6 octahedra, corners with two equivalent LiO6 octahedra, and corners with two equivalent VO4 tetrahedra. The corner-sharing octahedra tilt angles range from 33–61°. There is two shorter (1.68 Å) and two longer (1.83 Å) V–O bond length. In the second V5+ site, V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share a cornercorner with one LiO6 octahedra, corners with two equivalent NaO6 octahedra, and corners with two equivalent VO4 tetrahedra. The corner-sharing octahedra tilt angles range from 35–63°. 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+ and two V5+ atoms. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+ and two V5+ atoms. In the third O2- site, O2- is bonded in a distorted T-shaped geometry to one Na1+, one Li1+, and one V5+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to two Na1+ and one V5+ atom. In the fifth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two Na1+, one Li1+, and one V5+ atom. In the sixth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two Na1+, one Li1+, and one V5+ atom.
