The material described by MgGa crystallizes in the orthorhombic Amm2 space group. There are three inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 6-coordinate geometry to two equivalent Ga(1) and four equivalent Ga(2) atoms. In the second Mg site, Mg(2) is bonded in a 4-coordinate geometry to two equivalent Ga(1) and two equivalent Ga(3) atoms. In the third Mg site, Mg(3) is bonded to two equivalent Ga(2) and two equivalent Ga(3) atoms to form distorted edge-sharing MgGa4 cuboctahedra. There are three inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 4-coordinate geometry to two equivalent Mg(1) and two equivalent Mg(2) atoms. In the second Ga site, Ga(2) is bonded in a 6-coordinate geometry to two equivalent Mg(3) and four equivalent Mg(1) atoms. In the third Ga site, Ga(3) is bonded in a 4-coordinate geometry to two equivalent Mg(2) and two equivalent Mg(3) atoms. is represented by the CIF card [CIF]
