Li3Ga2 crystallizes in the trigonal R-3m space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a 4-coordinate geometry to three equivalent Li(2) and four equivalent Ga(1) atoms. In the second Li site, Li(2) is bonded in a distorted linear geometry to six equivalent Li(1) and eight equivalent Ga(1) atoms. Ga(1) is bonded in a 5-coordinate geometry to four equivalent Li(1) and four equivalent Li(2) atoms.
Li3Ga2 crystallizes in the trigonal R-3m space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a 4-coordinate geometry to three equivalent Li(2) and four equivalent Ga(1) atoms. All Li(1)-Li(2) bond lengths are 2.67 Å. There are three shorter (2.63 Å) and one longer (2.80 Å) Li(1)-Ga(1) bond length. In the second Li site, Li(2) is bonded in a distorted linear geometry to six equivalent Li(1) and eight equivalent Ga(1) atoms. There are two shorter (2.74 Å) and six longer (3.09 Å) Li(2)-Ga(1) bond lengths. Ga(1) is bonded in a 5-coordinate geometry to four equivalent Li(1) and four equivalent Li(2) atoms.
