The compound described by MgGa2 crystallizes in the orthorhombic Cmcm space group. Mg(1) is bonded in a 10-coordinate geometry to four equivalent Ga(2) and six equivalent Ga(1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 10-coordinate geometry to six equivalent Mg(1), two equivalent Ga(1), and two equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded in a 4-coordinate geometry to four equivalent Mg(1) and two equivalent Ga(1) atoms. is represented by the CIF card [CIF]
