The structure described by Mg2Ga5 crystallizes in the tetragonal I4/mmm space group. Mg(1) is bonded in a 10-coordinate geometry to two equivalent Ga(2) and eight equivalent Ga(1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 8-coordinate geometry to four equivalent Mg(1), one Ga(2), and three equivalent Ga(1) atoms. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to four equivalent Mg(1), one Ga(2), and four equivalent Ga(1) atoms. is represented by the CIF card [CIF]
