The material structure described by MgGa5 crystallizes in the monoclinic Cm space group. Mg(1) is bonded in a 10-coordinate geometry to one Ga(4), two equivalent Ga(1), two equivalent Ga(3), two equivalent Ga(5), and three equivalent Ga(2) atoms. There are five inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 10-coordinate geometry to two equivalent Mg(1), one Ga(3), two equivalent Ga(2), two equivalent Ga(4), and three equivalent Ga(5) atoms. In the second Ga site, Ga(2) is bonded in a 10-coordinate geometry to three equivalent Mg(1), one Ga(5), two equivalent Ga(1), two equivalent Ga(3), and two equivalent Ga(4) atoms. In the third Ga site, Ga(3) is bonded in a 10-coordinate geometry to two equivalent Mg(1), one Ga(1), two equivalent Ga(2), two equivalent Ga(5), and three equivalent Ga(4) atoms. In the fourth Ga site, Ga(4) is bonded in a distorted single-bond geometry to one Mg(1), two equivalent Ga(1), two equivalent Ga(2), two equivalent Ga(5), and three equivalent Ga(3) atoms. In the fifth Ga site, Ga(5) is bonded in a 10-coordinate geometry to two equivalent Mg(1), one Ga(2), two equivalent Ga(3), two equivalent Ga(4), and three equivalent Ga(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
