The material described by MgGa2 crystallizes in the orthorhombic Pbam space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 10-coordinate geometry to two equivalent Ga(2), two equivalent Ga(3), two equivalent Ga(4), and four equivalent Ga(1) atoms. In the second Mg site, Mg(2) is bonded in a 9-coordinate geometry to one Ga(3), two equivalent Ga(1), four equivalent Ga(2), and four equivalent Ga(4) atoms. There are four inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 11-coordinate geometry to two equivalent Mg(2), four equivalent Mg(1), one Ga(1), one Ga(2), one Ga(4), and two equivalent Ga(3) atoms. In the second Ga site, Ga(2) is bonded in a 11-coordinate geometry to two equivalent Mg(1), four equivalent Mg(2), one Ga(1), two equivalent Ga(3), and two equivalent Ga(4) atoms. In the third Ga site, Ga(3) is bonded in a 8-coordinate geometry to one Mg(2), two equivalent Mg(1), one Ga(3), two equivalent Ga(1), and two equivalent Ga(2) atoms. In the fourth Ga site, Ga(4) is bonded in a 9-coordinate geometry to two equivalent Mg(1), four equivalent Mg(2), one Ga(1), and two equivalent Ga(2) atoms. is represented by the CIF file [CIF]
