Title: Materials Data on Li3AlSiO5 by Materials Project

Abstract

Li3AlSiO5 is beta beryllia-derived structured and crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with three equivalent SiO4 tetrahedra, corners with four equivalent AlO4 tetrahedra, and corners with five LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.92–2.10 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share a cornercorner with one AlO4 tetrahedra, corners with four equivalent SiO4 tetrahedra, and corners with seven LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.97–2.09 Å. In the third Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with three equivalent AlO4 tetrahedra, corners with three equivalent SiO4 tetrahedra, and corners with six LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.94–2.12 Å. Al3+ is bonded to four O2- atoms to form AlO4 tetrahedra that share corners with two equivalent AlO4 tetrahedra, corners with two equivalent SiO4 tetrahedra, and corners with eight LiO4 tetrahedra. There aremore » a spread of Al–O bond distances ranging from 1.77–1.80 Å. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with two equivalent AlO4 tetrahedra and corners with ten LiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.62–1.70 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded to two Li1+, one Al3+, and one Si4+ atom to form corner-sharing OLi2AlSi tetrahedra. In the second O2- site, O2- is bonded to two Li1+ and two equivalent Al3+ atoms to form distorted corner-sharing OLi2Al2 tetrahedra. In the third O2- site, O2- is bonded to three Li1+ and one Si4+ atom to form distorted corner-sharing OLi3Si tetrahedra. In the fourth O2- site, O2- is bonded to three Li1+ and one Si4+ atom to form distorted corner-sharing OLi3Si tetrahedra. In the fifth O2- site, O2- is bonded to two equivalent Li1+, one Al3+, and one Si4+ atom to form corner-sharing OLi2AlSi tetrahedra.« less
