The material structure described by MgLa4Ru 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 face and corner-sharing MgLa9Mg3 cuboctahedra. There are three inequivalent La sites. In the first La site, La(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Mg(1) and two equivalent Ru(1) atoms. In the second La site, La(2) is bonded in a 3-coordinate geometry to three equivalent Mg(1) and three equivalent Ru(1) atoms. In the third La site, La(3) is bonded in a bent 150 degrees geometry to two equivalent Mg(1) and two equivalent Ru(1) atoms. Ru(1) is bonded in a 6-coordinate geometry to three equivalent La(1), three equivalent La(2), and three equivalent La(3) atoms. is represented by the CIF file [CIF]
