Materials Data on NaNb3(TeO4)4 by Materials Project
NaNb3(TeO4)4 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Na1+ is bonded in a distorted body-centered cubic geometry to eight O2- atoms. There are a spread of Na–O bond distances ranging from 2.52–2.93 Å. There are two inequivalent Nb5+ sites. In the first Nb5+ site, Nb5+ is bonded to six O2- atoms to form corner-sharing NbO6 octahedra. The corner-sharing octahedra tilt angles range from 15–36°. There are a spread of Nb–O bond distances ranging from 1.88–2.20 Å. In the second Nb5+ site, Nb5+ is bonded to six O2- atoms to form corner-sharing NbO6 octahedra. The corner-sharing octahedra tilt angles range from 15–32°. There are a spread of Nb–O bond distances ranging from 1.97–2.03 Å. There are four inequivalent Te4+ sites. In the first Te4+ site, Te4+ is bonded in a 3-coordinate geometry to three O2- atoms. There is one shorter (1.84 Å) and two longer (1.94 Å) Te–O bond length. In the second Te4+ site, Te4+ is bonded in a 4-coordinate geometry to six O2- atoms. There are a spread of Te–O bond distances ranging from 1.93–2.80 Å. In the third Te4+ site, Te4+ is bonded in a 4-coordinate geometry to six O2- atoms. There are a spread of Te–O bond distances ranging from 1.91–2.92 Å. In the fourth Te4+ site, Te4+ is bonded in a 6-coordinate geometry to three O2- atoms. There is one shorter (1.87 Å) and two longer (1.95 Å) Te–O bond length. There are eleven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Nb5+ and one Te4+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Nb5+ atoms. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Nb5+ atoms. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Na1+, one Nb5+, and two Te4+ atoms. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Nb5+ and one Te4+ atom. In the sixth O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Na1+ and two Te4+ atoms. In the seventh O2- site, O2- is bonded in a bent 150 degrees geometry to two equivalent Nb5+ atoms. In the eighth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two Te4+ atoms. In the ninth O2- site, O2- is bonded to two equivalent Na1+ and two Te4+ atoms to form distorted corner-sharing ONa2Te2 tetrahedra. In the tenth O2- site, O2- is bonded in a linear geometry to two Nb5+ atoms. In the eleventh O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one Nb5+, and two equivalent Te4+ atoms.
