RhCd2 is alpha carbon monoxide-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two RhCd2 clusters. Rh(1) is bonded in a single-bond geometry to one Cd(1) atom. The Rh(1)-Cd(1) bond length is 0.14 Å. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a single-bond geometry to one Rh(1) and one Cd(2) atom. The Cd(1)-Cd(2) bond length is 1.52 Å. In the second Cd site, Cd(2) is bonded in a single-bond geometry to one Cd(1) atom.
