Materials Data on LiTi(SiO3)2 by Materials Project
LiTiSi2O6 is Esseneite structured and crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Li1+ is bonded to six O2- atoms to form distorted LiO6 octahedra that share corners with four equivalent SiO4 tetrahedra, edges with three equivalent TiO6 octahedra, and edges with two equivalent SiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 2.10–2.37 Å. Ti3+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six equivalent SiO4 tetrahedra, edges with two equivalent TiO6 octahedra, and edges with three equivalent LiO6 octahedra. There are a spread of Ti–O bond distances ranging from 1.97–2.13 Å. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with two equivalent LiO6 octahedra, corners with three equivalent TiO6 octahedra, corners with two equivalent SiO4 tetrahedra, and an edgeedge with one LiO6 octahedra. The corner-sharing octahedra tilt angles range from 29–61°. There is one shorter (1.61 Å) and three longer (1.65 Å) Si–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+ and two equivalent Si4+ atoms. In the second O2- site, O2- is bonded in a distorted T-shaped geometry to one Li1+, one Ti3+, and one Si4+ atom. In the third O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Li1+, two equivalent Ti3+, and one Si4+ atom.
