MgLa crystallizes in the orthorhombic Amm2 space group. There are three inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a body-centered cubic geometry to two equivalent La(1), two equivalent La(2), and four equivalent La(3) atoms. In the second Mg site, Mg(2) is bonded in a 10-coordinate geometry to two equivalent Mg(3), two equivalent La(1), two equivalent La(3), and four equivalent La(2) atoms. In the third Mg site, Mg(3) is bonded in a body-centered cubic geometry to two equivalent Mg(2), two equivalent La(3), and four equivalent La(1) atoms. There are three inequivalent La sites. In the first La site, La(1) is bonded in a 10-coordinate geometry to two equivalent Mg(1), two equivalent Mg(2), four equivalent Mg(3), and two equivalent La(2) atoms. In the second La site, La(2) is bonded in a 8-coordinate geometry to two equivalent Mg(1), four equivalent Mg(2), and two equivalent La(1) atoms. In the third La site, La(3) is bonded in a distorted body-centered cubic geometry to two equivalent Mg(2), two equivalent Mg(3), and four equivalent Mg(1) atoms.
