Materials Data on Li2AlSi by Materials Project

Abstract

Li2AlSi crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Li is bonded in a 1-coordinate geometry to four equivalent Li, three equivalent Al, and four equivalent Si atoms. There are three shorter (2.77 Å) and one longer (2.87 Å) Li–Li bond lengths. All Li–Al bond lengths are 2.87 Å. There are one shorter (2.65 Å) and three longer (2.87 Å) Li–Si bond lengths. Al is bonded in a 9-coordinate geometry to six equivalent Li and three equivalent Si atoms. All Al–Si bond lengths are 2.49 Å. Si is bonded in a 11-coordinate geometry to eight equivalent Li and three equivalent Al atoms.
