description: Li2Ti(BO3)2 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are four inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 trigonal pyramids that share a cornercorner with one TiO4 tetrahedra, corners with two equivalent LiO4 tetrahedra, and a cornercorner with one TiO5 trigonal bipyramid. There are a spread of Li–O bond distances ranging from 1.89–2.47 Å. In the second 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 1.90–2.67 Å. In the third Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with two equivalent TiO4 tetrahedra and corners with two equivalent LiO4 trigonal pyramids. There are a spread of Li–O bond distances ranging from 1.90–2.15 Å. In the fourth Li1+ site, Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.85–2.15 Å. There are two inequivalent Ti4+ sites. In the first Ti4+ site, Ti4+ is bonded to five O2- atoms to form TiO5 trigonal bipyramids that share a cornercorner with one LiO4 trigonal pyramid. There are a spread of Ti–O bond distances ranging from 1.83–2.12 Å. In the second Ti4+ site, Ti4+ is bonded to four O2- atoms to form TiO4 tetrahedra that share corners with two equivalent LiO4 tetrahedra and a cornercorner with one LiO4 trigonal pyramid. There are a spread of Ti–O bond distances ranging from 1.83–1.86 Å. There are four 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 1.34–1.43 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 1.31–1.45 Å. In the third B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.32 Å) and two longer (1.42 Å) B–O bond length. In the fourth 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 twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+, one Ti4+, and one B3+ atom. In the second O2- site, O2- is bonded in a trigonal planar geometry to one Li1+, one Ti4+, and one B3+ atom. In the third O2- site, O2- is bonded in a 4-coordinate geometry to two Li1+, one Ti4+, and one B3+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Li1+ and one B3+ atom. In the fifth O2- site, O2- is bonded in a trigonal planar geometry to two Li1+ 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. In the seventh O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Li1+, one Ti4+, and one B3+ atom. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to two Li1+ and one B3+ atom. In the ninth O2- site, O2- is bonded in a 4-coordinate geometry to two Li1+, one Ti4+, and one B3+ atom.
