Ga crystallizes in the trigonal R-3m space group. There are five inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 8-coordinate geometry to one Ga(2), one Ga(3), two equivalent Ga(4), and four equivalent Ga(1) atoms. In the second Ga site, Ga(2) is bonded in a 8-coordinate geometry to one Ga(1), one Ga(4), two equivalent Ga(2), and four equivalent Ga(3) atoms. In the third Ga site, Ga(3) is bonded in a 8-coordinate geometry to one Ga(1), one Ga(5), two equivalent Ga(4), and four equivalent Ga(2) atoms. In the fourth Ga site, Ga(4) is bonded in a distorted q6 geometry to two equivalent Ga(2), four equivalent Ga(1), and four equivalent Ga(3) atoms. In the fifth Ga site, Ga(5) is bonded in a 6-coordinate geometry to six equivalent Ga(3) atoms.

In the first Ga site, Ga(1) is bonded in a 8-coordinate geometry to one Ga(2), one Ga(3), two equivalent Ga(4), and four equivalent Ga(1) atoms. The Ga(1)-Ga(2) bond length is 2.57 Å. The Ga(1)-Ga(3) bond length is 2.80 Å. Both Ga(1)-Ga(4) bond lengths are 2.74 Å. There are two shorter (2.73 Å) and two longer (3.06 Å) Ga(1)-Ga(1) bond lengths. In the second Ga site, Ga(2) is bonded in a 8-coordinate geometry to one Ga(1), one Ga(4), two equivalent Ga(2), and four equivalent Ga(3) atoms. The Ga(2)-Ga(4) bond length is 2.82 Å. Both Ga(2)-Ga(2) bond lengths are 2.71 Å. There are two shorter (2.81 Å) and two longer (2.97 Å) Ga(2)-Ga(3) bond lengths. In the third Ga site, Ga(3) is bonded in a 8-coordinate geometry to one Ga(1), one Ga(5), two equivalent Ga(4), and four equivalent Ga(2) atoms. The Ga(3)-Ga(5) bond length is 2.75 Å. Both Ga(3)-Ga(4) bond lengths are 2.85 Å. In the fourth Ga site, Ga(4) is bonded in a distorted q6 geometry to two equivalent Ga(2), four equivalent Ga(1), and four equivalent Ga(3) atoms. In the fifth Ga site, Ga(5) is bonded in a 6-coordinate geometry to six equivalent Ga(3) atoms.
