The structure described by Ce4RuMg crystallizes in the cubic F-43m space group. Mg(1) is bonded to three equivalent Mg(1), three equivalent Ce(1), three equivalent Ce(2), and three equivalent Ce(3) atoms to form a mixture of face and corner-sharing MgCe9Mg3 cuboctahedra. There are three inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 3-coordinate geometry to three equivalent Mg(1) and three equivalent Ru(1) atoms. In the second Ce site, Ce(2) is bonded in a 4-coordinate geometry to two equivalent Mg(1) and two equivalent Ru(1) atoms. In the third Ce site, Ce(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 Ce(1), three equivalent Ce(2), and three equivalent Ce(3) atoms. is represented by the CIF file [CIF]
