The structure described by 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. is represented by the CIF file [CIF]
