Materials Data on LiNb(BO3)2 by Materials Project
LiNb(BO3)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.98–2.09 Å. Nb5+ is bonded in a distorted octahedral geometry to six O2- atoms. There are a spread of Nb–O bond distances ranging from 1.94–2.25 Å. There are two inequivalent B3+ sites. In the first B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of B–O bond distances ranging from 1.37–1.42 Å. In the second B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of B–O bond distances ranging from 1.37–1.39 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Nb5+ and one B3+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Nb5+, and one B3+ atom. In the third O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Li1+, one Nb5+, and one B3+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Nb5+, and one B3+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Nb5+ and one B3+ atom. In the sixth O2- site, O2- is bonded in an L-shaped geometry to one Nb5+ and one B3+ atom.
