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