MgLa4Ni crystallizes in the cubic F-43m space group. Mg(1) is bonded to three equivalent Mg(1), three equivalent La(1), three equivalent La(2), and three equivalent La(3) atoms to form a mixture of corner and face-sharing MgLa9Mg3 cuboctahedra. There are three inequivalent La sites. In the first La site, La(1) is bonded in a 3-coordinate geometry to three equivalent Mg(1), three equivalent La(3), and three equivalent Ni(1) atoms. In the second La site, La(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Mg(1), four equivalent La(3), and two equivalent Ni(1) atoms. In the third La site, La(3) is bonded in a 14-coordinate geometry to two equivalent Mg(1), two equivalent La(1), four equivalent La(2), four equivalent La(3), and two equivalent Ni(1) atoms. Ni(1) is bonded in a 6-coordinate geometry to three equivalent La(1), three equivalent La(2), and three equivalent La(3) atoms.
