Materials Data on Na3VO3 by Materials Project
Na3VO3 is Ilmenite-like structured and crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are four inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to four O2- atoms to form distorted NaO4 tetrahedra that share corners with five equivalent VO4 tetrahedra, corners with six NaO4 tetrahedra, and edges with two equivalent NaO4 tetrahedra. There are a spread of Na–O bond distances ranging from 2.33–2.53 Å. In the second Na1+ site, Na1+ is bonded to four O2- atoms to form NaO4 tetrahedra that share corners with three equivalent VO4 tetrahedra, corners with six NaO4 tetrahedra, and an edgeedge with one VO4 tetrahedra. There are a spread of Na–O bond distances ranging from 2.32–2.46 Å. In the third 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 2.39–2.96 Å. In the fourth Na1+ site, Na1+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are two shorter (2.30 Å) and two longer (2.45 Å) Na–O bond lengths. V3+ is bonded to four O2- atoms to form VO4 tetrahedra that share corners with eight NaO4 tetrahedra, an edgeedge with one NaO4 tetrahedra, and an edgeedge with one VO4 tetrahedra. There are a spread of V–O bond distances ranging from 1.90–2.01 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to three Na1+ and two equivalent V3+ atoms. In the second O2- site, O2- is bonded to five Na1+ and one V3+ atom to form a mixture of distorted corner and edge-sharing ONa5V octahedra. The corner-sharing octahedral tilt angles are 18°. In the third O2- site, O2- is bonded in a 6-coordinate geometry to five Na1+ and one V3+ atom.
