MgGa crystallizes in the monoclinic C2 space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 8-coordinate geometry to four equivalent Mg(2), two equivalent Ga(2), and six equivalent Ga(1) atoms. In the second Mg site, Mg(2) is bonded in a 12-coordinate geometry to two equivalent Mg(1), three equivalent Mg(2), three equivalent Ga(2), and four equivalent Ga(1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 11-coordinate geometry to three equivalent Mg(1), four equivalent Mg(2), one Ga(2), and three equivalent Ga(1) atoms. In the second Ga site, Ga(2) is bonded in a 8-coordinate geometry to two equivalent Mg(1), six equivalent Mg(2), and two equivalent Ga(1) atoms.

In the first Mg site, Mg(1) is bonded in a 8-coordinate geometry to four equivalent Mg(2), two equivalent Ga(2), and six equivalent Ga(1) atoms. There are two shorter (3.06 Å) and two longer (3.13 Å) Mg(1)-Mg(2) bond lengths. Both Mg(1)-Ga(2) bond lengths are 2.88 Å. There are a spread of Mg(1)-Ga(1) bond distances ranging from 2.92-3.01 Å. In the second Mg site, Mg(2) is bonded in a 12-coordinate geometry to two equivalent Mg(1), three equivalent Mg(2), three equivalent Ga(2), and four equivalent Ga(1) atoms. There is one shorter (2.96 Å) and two longer (2.98 Å) Mg(2)-Mg(2) bond lengths. There are a spread of Mg(2)-Ga(2) bond distances ranging from 2.96-2.99 Å.
