Materials Data on Li3Al2 by Materials Project
Al2Li3 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are two inequivalent Li sites. In the first Li site, Li is bonded in a 4-coordinate geometry to four equivalent Al atoms. There are three shorter (2.73 Å) and one longer (2.90 Å) Li–Al bond lengths. In the second Li site, Li is bonded in a distorted linear geometry to two equivalent Al atoms. Both Li–Al bond lengths are 2.81 Å. Al is bonded in a 8-coordinate geometry to five Li atoms.
