Mg3Ga crystallizes in the orthorhombic Pmm2 space group. There are three inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 4-coordinate geometry to four equivalent Ga(1) atoms. In the second Mg site, Mg(2) is bonded in a 4-coordinate geometry to four equivalent Ga(1) atoms. In the third Mg site, Mg(3) is bonded in a 2-coordinate geometry to two equivalent Ga(1) atoms. Ga(1) is bonded in a distorted q6 geometry to two equivalent Mg(3), four equivalent Mg(1), and four equivalent Mg(2) atoms.
Mg3Ga crystallizes in the orthorhombic Pmm2 space group. There are three inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 4-coordinate geometry to four equivalent Ga(1) atoms. There are two shorter (3.02 Å) and two longer (3.05 Å) Mg(1)-Ga(1) bond lengths. In the second Mg site, Mg(2) is bonded in a 4-coordinate geometry to four equivalent Ga(1) atoms. All Mg(2)-Ga(1) bond lengths are 3.01 Å. In the third Mg site, Mg(3) is bonded in a 2-coordinate geometry to two equivalent Ga(1) atoms. Both Mg(3)-Ga(1) bond lengths are 3.01 Å. Ga(1) is bonded in a distorted q6 geometry to two equivalent Mg(3), four equivalent Mg(1), and four equivalent Mg(2) atoms.
