Materials Data on Li2Ga by Materials Project
Li2Ga crystallizes in the orthorhombic Cmcm space group. The structure is two-dimensional and consists of two Li2Ga sheets oriented in the (0, 1, 0) direction. there are two inequivalent Li sites. In the first Li site, Li is bonded in a distorted water-like geometry to two equivalent Ga atoms. Both Li–Ga bond lengths are 2.75 Å. In the second Li site, Li is bonded in a 4-coordinate geometry to four equivalent Ga atoms. There are two shorter (2.67 Å) and two longer (2.82 Å) Li–Ga bond lengths. Ga is bonded in a 6-coordinate geometry to six Li atoms.
