Title: Materials Data on LiAl(SiO3)2 by Materials Project

Abstract

LiAlSi2O6 is Esseneite structured and crystallizes in the monoclinic C2/c 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 2.11–2.30 Å. Al3+ is bonded to six O2- atoms to form AlO6 octahedra that share corners with six equivalent SiO4 tetrahedra and edges with two equivalent AlO6 octahedra. There are a spread of Al–O bond distances ranging from 1.84–2.03 Å. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with three equivalent AlO6 octahedra and corners with two equivalent SiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 30–60°. There are a spread of Si–O bond distances ranging from 1.60–1.66 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+ and two equivalent Si4+ atoms. In the second O2- site, O2- is bonded to one Li1+, two equivalent Al3+, and one Si4+ atom to form a mixture of distorted corner and edge-sharing OLiAl2Si tetrahedra. In the third O2- site, O2- is bonded in a distorted T-shaped geometry to one Li1+, one Al3+, and one Si4+ atom.
