Materials Data on NaVTeO5 by Materials Project
NaVTeO5 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Na1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Na–O bond distances ranging from 2.42–2.86 Å. V5+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of V–O bond distances ranging from 1.67–1.85 Å. Te4+ is bonded in a 4-coordinate geometry to six O2- atoms. There are a spread of Te–O bond distances ranging from 1.94–2.77 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Na1+ and two equivalent Te4+ atoms. In the second O2- site, O2- is bonded in a 1-coordinate geometry to one V5+ and two equivalent Te4+ atoms. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Na1+, one V5+, and one Te4+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Na1+, one V5+, and one Te4+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Na1+ and one V5+ atom.
