Li3Ga7 crystallizes in the trigonal R-3m space group. Li(1) is bonded in a 9-coordinate geometry to one Ga(3), four equivalent Ga(1), and four equivalent Ga(2) atoms. There are three inequivalent Ga sites. In the first Ga site, Ga(3) is bonded in a distorted hexagonal pyramidal geometry to three equivalent Li(1), one Ga(3), and three equivalent Ga(2) atoms. In the second Ga site, Ga(1) is bonded in a 10-coordinate geometry to four equivalent Li(1), three equivalent Ga(1), and three equivalent Ga(2) atoms. In the third Ga site, Ga(2) is bonded in a 10-coordinate geometry to four equivalent Li(1), one Ga(3), two equivalent Ga(2), and three equivalent Ga(1) atoms.
Li3Ga7 crystallizes in the trigonal R-3m space group. Li(1) is bonded in a 9-coordinate geometry to one Ga(3), four equivalent Ga(1), and four equivalent Ga(2) atoms. The Li(1)-Ga(3) bond length is 2.90 Å. There are two shorter (2.87 Å) and two longer (2.93 Å) Li(1)-Ga(1) bond lengths. There are two shorter (2.83 Å) and two longer (2.96 Å) Li(1)-Ga(2) bond lengths. There are three inequivalent Ga sites. In the first Ga site, Ga(3) is bonded in a distorted hexagonal pyramidal geometry to three equivalent Li(1), one Ga(3), and three equivalent Ga(2) atoms. The Ga(3)-Ga(3) bond length is 2.64 Å. All Ga(3)-Ga(2) bond lengths are 2.53 Å. In the second Ga site, Ga(1) is bonded in a 10-coordinate geometry to four equivalent Li(1), three equivalent Ga(1), and three equivalent Ga(2) atoms. There is one shorter (2.51 Å) and two longer (2.67 Å) Ga(1)-Ga(1) bond lengths. There are two shorter (2.64 Å) and one longer (2.67 Å) Ga(1)-Ga(2) bond length. In the third Ga site, Ga(2) is bonded in a 10-coordinate geometry to four equivalent Li(1), one Ga(3), two equivalent Ga(2), and three equivalent Ga(1) atoms. Both Ga(2)-Ga(2) bond lengths are 2.74 Å.
