MgGa2 is Cuprite structured and crystallizes in the tetragonal P4_2/mnm space group. Mg(1) is bonded to six equivalent Ga(1) atoms to form a mixture of distorted edge and corner-sharing MgGa6 octahedra. The corner-sharing octahedral tilt angles are 64°. Ga(1) is bonded in a 4-coordinate geometry to three equivalent Mg(1) and one Ga(1) atom.

Mg(1) is bonded to six equivalent Ga(1) atoms to form a mixture of distorted edge and corner-sharing MgGa6 octahedra. The corner-sharing octahedral tilt angles are 64°. There are two shorter (2.64 Å) and four longer (2.85 Å) Mg(1)-Ga(1) bond lengths. Ga(1) is bonded in a 4-coordinate geometry to three equivalent Mg(1) and one Ga(1) atom. The Ga(1)-Ga(1) bond length is 2.49 Å.
