Materials Data on Li3Ga2 by Materials Project
Li3Ga2 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 distorted linear geometry to two equivalent Ga atoms. Both Li–Ga bond lengths are 2.78 Å. In the second Li site, Li is bonded to four equivalent Ga atoms to form a mixture of distorted corner and edge-sharing LiGa4 tetrahedra. There are three shorter (2.66 Å) and one longer (2.82 Å) Li–Ga bond lengths. Ga is bonded in a 5-coordinate geometry to five Li atoms.
