Mg Mg Cd Rh
Mg2RhCd crystallizes in the triclinic P1 space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded in a 2-coordinate geometry to one Mg(2), two equivalent Rh(1), and one Cd(1) atom. The Mg(1)-Mg(2) bond length is 1.67 Å. There is one shorter (1.60 Å) and one longer (2.07 Å) Mg(1)-Rh(1) bond length. The Mg(1)-Cd(1) bond length is 2.23 Å. In the second Mg site, Mg(2) is bonded in a 4-coordinate geometry to one Mg(1), one Rh(1), and two equivalent Cd(1) atoms. The Mg(2)-Rh(1) bond length is 2.02 Å. There is one shorter (2.10 Å) and one longer (2.90 Å) Mg(2)-Cd(1) bond length. Rh(1) is bonded in a distorted rectangular see-saw-like geometry to one Mg(2), two equivalent Mg(1), and one Cd(1) atom. The Rh(1)-Cd(1) bond length is 2.34 Å. Cd(1) is bonded in a 4-coordinate geometry to one Mg(1), two equivalent Mg(2), and one Rh(1) atom.
