MgNd4Ru crystallizes in the cubic F-43m space group. Mg(1) is bonded to three equivalent Mg(1), three equivalent Nd(1), three equivalent Nd(2), and three equivalent Nd(3) atoms to form a mixture of face and corner-sharing MgNd9Mg3 cuboctahedra. There are three inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a bent 150 degrees geometry to two equivalent Mg(1) and two equivalent Ru(1) atoms. In the second Nd site, Nd(2) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Mg(1) and two equivalent Ru(1) atoms. In the third Nd site, Nd(3) is bonded in a 3-coordinate geometry to three equivalent Mg(1) and three equivalent Ru(1) atoms. Ru(1) is bonded in a 6-coordinate geometry to three equivalent Nd(1), three equivalent Nd(2), and three equivalent Nd(3) atoms.
