Materials Data on Li2Ti(BO3)2 by Materials Project

Abstract

Li2Ti(BO3)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Li–O bond distances ranging from 1.95–2.52 Å. In the second Li1+ site, Li1+ is bonded in a 4-coordinate geometry to five O2- atoms. There are a spread of Li–O bond distances ranging from 1.95–2.64 Å. Ti4+ is bonded in a trigonal bipyramidal geometry to five O2- atoms. There are a spread of Ti–O bond distances ranging from 1.84–2.06 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 is one shorter (1.34 Å) and two longer (1.41 Å) B–O bond length. In the second B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.38 Å) and one longer (1.39 Å) B–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 Ti4+, and one B3+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two Li1+, one Ti4+, and one B3+ atom. In the third O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to three Li1+ and one B3+ atom. In the fourth O2- site, O2- is bonded in a distorted tetrahedral geometry to two Li1+, one Ti4+, and one B3+ atom. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+, one Ti4+, and one B3+ atom. In the sixth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Li1+, one Ti4+, and one B3+ atom.
