The material described by Mg2Ga crystallizes in the monoclinic C2/m space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 5-coordinate geometry to five equivalent Ga(1) atoms. In the second Mg site, Mg(2) is bonded in a 4-coordinate geometry to four equivalent Ga(1) atoms. Ga(1) is bonded in a 9-coordinate geometry to four equivalent Mg(2) and five equivalent Mg(1) atoms. is represented by the CIF card [CIF]
