LiNb(TeO4)3 crystallizes in the monoclinic P2 space group. The structure is three-dimensional. Li1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Li–O bond distances ranging from 2.02–2.43 Å. Nb5+ is bonded to six O2- atoms to form NbO6 octahedra that share corners with two equivalent TeO6 octahedra and edges with two equivalent TeO6 octahedra. The corner-sharing octahedral tilt angles are 39°. There are a spread of Nb–O bond distances ranging from 2.00–2.05 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 NbO6 octahedra and edges with two equivalent TeO6 octahedra. The corner-sharing octahedral tilt angles are 39°. There are a spread of Te–O bond distances ranging from 1.93–1.99 Å. In the second Te6+ site, Te6+ is bonded to six O2- atoms to form a mixture of corner and edge-sharing TeO6 octahedra. The corner-sharing octahedral tilt angles are 44°. There are a spread of Te–O bond distances ranging from 1.93–2.03 Å. In the third Te6+ site, Te6+ is bonded to six O2- atoms to form TeO6 octahedra that share corners with two equivalent TeO6 octahedra and edges with two equivalent NbO6 octahedra. The corner-sharing octahedral tilt angles are 44°. There is two shorter (1.91 Å) and four longer (1.98 Å) Te–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Nb5+, and one Te6+ atom. In the second O2- site, O2- is bonded in a water-like geometry to two Te6+ atoms. In the third O2- site, O2- is bonded in a water-like geometry to one Nb5+ and one Te6+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Li1+ and 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 bent 150 degrees geometry to two Te6+ atoms.
