Na Na Cd Rh
Na2RhCd crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Na2RhCd clusters. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 2-coordinate geometry to one Rh(1) and one Cd(1) atom. The Na(1)-Rh(1) bond length is 1.60 Å. The Na(1)-Cd(1) bond length is 1.38 Å. In the second Na site, Na(2) is bonded in a single-bond geometry to one Rh(1) and one Cd(1) atom. The Na(2)-Rh(1) bond length is 1.55 Å. The Na(2)-Cd(1) bond length is 0.13 Å. Rh(1) is bonded in a 2-coordinate geometry to one Na(1) and one Na(2) atom. Cd(1) is bonded in a single-bond geometry to one Na(1) and one Na(2) atom.
