The structure described by MgTm4Rh crystallizes in the cubic F-43m space group. Mg(1) is bonded to three equivalent Mg(1), three equivalent Tm(1), three equivalent Tm(2), and three equivalent Tm(3) atoms to form a mixture of face and corner-sharing MgTm9Mg3 cuboctahedra. There are three inequivalent Tm sites. In the first Tm site, Tm(1) is bonded in a 3-coordinate geometry to three equivalent Mg(1), three equivalent Tm(3), and three equivalent Rh(1) atoms. In the second Tm site, Tm(2) is bonded in a bent 150 degrees geometry to two equivalent Mg(1), four equivalent Tm(3), and two equivalent Rh(1) atoms. In the third Tm site, Tm(3) is bonded in a 14-coordinate geometry to two equivalent Mg(1), two equivalent Tm(1), four equivalent Tm(2), four equivalent Tm(3), and two equivalent Rh(1) atoms. Rh(1) is bonded in a 6-coordinate geometry to three equivalent Tm(1), three equivalent Tm(2), and three equivalent Tm(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
