Materials Data on LiAlSi2O7 by Materials Project
Abstract
LiAlSi2O7 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are two inequivalent Li sites. In the first Li site, Li is bonded to four O atoms to form distorted LiO4 tetrahedra that share corners with three AlO4 tetrahedra and corners with three SiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.95–2.54 Å. In the second Li site, Li is bonded in a trigonal planar geometry to three O atoms. There are a spread of Li–O bond distances ranging from 1.92–1.94 Å. There are two inequivalent Al sites. In the first Al site, Al is bonded to four O atoms to form AlO4 tetrahedra that share corners with two equivalent LiO4 tetrahedra and corners with four SiO4 tetrahedra. There is one shorter (1.73 Å) and three longer (1.78 Å) Al–O bond length. In the second Al site, Al is bonded to four O atoms to form AlO4 tetrahedra that share a cornercorner with one LiO4 tetrahedra and corners with four SiO4 tetrahedra. There are a spread of Al–O bond distances ranging from 1.73–1.79 Å. There are four inequivalent Si sites. In the first Si site, Si is bonded to four O atoms tomore »
