Na2RhCl is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Na2RhCl clusters. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a single-bond geometry to one Rh(1) atom. The Na(1)-Rh(1) bond length is 1.29 Å. In the second Na site, Na(2) is bonded in a distorted linear geometry to one Rh(1) and one Cl(1) atom. The Na(2)-Rh(1) bond length is 1.29 Å. The Na(2)-Cl(1) bond length is 0.52 Å. Rh(1) is bonded in a linear geometry to one Na(1) and one Na(2) atom. Cl(1) is bonded in a single-bond geometry to one Na(2) atom.
