MgRh2Cd crystallizes in the monoclinic Cm space group. Mg(1) is bonded in a 5-coordinate geometry to four equivalent Rh(2) and one Cd(1) atom. There are a spread of Mg(1)-Rh(2) bond distances ranging from 1.99-2.69 Å. The Mg(1)-Cd(1) bond length is 1.30 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 9-coordinate geometry to one Rh(2), four equivalent Rh(1), and four equivalent Cd(1) atoms. The Rh(1)-Rh(2) bond length is 2.46 Å. All Rh(1)-Rh(1) bond lengths are 3.16 Å. There are a spread of Rh(1)-Cd(1) bond distances ranging from 2.72-3.27 Å. In the second Rh site, Rh(2) is bonded in a 3-coordinate geometry to four equivalent Mg(1) and one Rh(1) atom. Cd(1) is bonded in a single-bond geometry to one Mg(1) and four equivalent Rh(1) atoms.
