Materials Data on LiNb(TeO4)3 by Materials Project

Abstract

LiNb(TeO4)3 crystallizes in the triclinic P1 space group. The structure is three-dimensional. Li1+ is bonded in a 3-coordinate geometry to six O2- atoms. There are a spread of Li–O bond distances ranging from 1.95–2.46 Å. Nb5+ is bonded to six O2- atoms to form NbO6 octahedra that share corners with six TeO6 octahedra. The corner-sharing octahedra tilt angles range from 32–40°. There are a spread of Nb–O bond distances ranging from 1.96–2.05 Å. There are three inequivalent Te6+ sites. In the first Te6+ site, Te6+ is bonded to six O2- atoms to form TeO6 octahedra that share corners with two equivalent TeO6 octahedra and corners with four equivalent NbO6 octahedra. The corner-sharing octahedra tilt angles range from 32–40°. There are a spread of Te–O bond distances ranging from 1.91–2.04 Å. In the second Te6+ site, Te6+ is bonded to six O2- atoms to form TeO6 octahedra that share corners with two equivalent NbO6 octahedra and corners with four equivalent TeO6 octahedra. The corner-sharing octahedra tilt angles range from 32–39°. There are a spread of Te–O bond distances ranging from 1.90–2.00 Å. In the third Te6+ site, Te6+ is bonded to six O2- atoms to form corner-sharing TeO6 octahedra. The corner-sharing octahedra tilt angles range from 38–40°. There are a spread of Te–O bond distances ranging from 1.94–1.98 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to two Te6+ atoms. In the second O2- site, O2- is bonded in a distorted T-shaped geometry to one Li1+, one Nb5+, and one Te6+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one Nb5+ and one Te6+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to two Te6+ atoms. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Nb5+, and one Te6+ atom. In the sixth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+ and two Te6+ atoms. In the seventh O2- site, O2- is bonded in a bent 150 degrees geometry to two Te6+ atoms. In the eighth O2- site, O2- is bonded in a distorted T-shaped geometry to one Li1+, one Nb5+, and one Te6+ atom. In the ninth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+ and two Te6+ atoms. In the tenth O2- site, O2- is bonded in a distorted T-shaped geometry to one Li1+, one Nb5+, and one Te6+ atom. In the eleventh O2- site, O2- is bonded in a bent 150 degrees geometry to one Nb5+ and one Te6+ atom. In the twelfth O2- site, O2- is bonded in a bent 150 degrees geometry to two Te6+ atoms.
