The structure described by MgEu2Ga3 crystallizes in the monoclinic Cm space group. Mg(1) is bonded in a 4-coordinate geometry to three equivalent Eu(1), three equivalent Eu(2), one Ga(1), one Ga(3), and two equivalent Ga(2) atoms. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded in a 12-coordinate geometry to three equivalent Mg(1), three equivalent Ga(1), three equivalent Ga(2), and three equivalent Ga(3) atoms. In the second Eu site, Eu(2) is bonded in a 12-coordinate geometry to three equivalent Mg(1), three equivalent Ga(1), three equivalent Ga(2), and three equivalent Ga(3) atoms. There are three inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 10-coordinate geometry to one Mg(1), three equivalent Eu(1), three equivalent Eu(2), one Ga(2), and two equivalent Ga(3) atoms. In the second Ga site, Ga(2) is bonded in a 10-coordinate geometry to two equivalent Mg(1), three equivalent Eu(1), three equivalent Eu(2), one Ga(1), and one Ga(3) atom. In the third Ga site, Ga(3) is bonded in a 10-coordinate geometry to one Mg(1), three equivalent Eu(1), three equivalent Eu(2), one Ga(2), and two equivalent Ga(1) atoms. is represented by the CIF file [CIF]
